Seismic Evaluation and Rehabilitation of Steel Structures in the United States
Authors: leon Roberto T. , Harris Jay , Paulson Conrad
Published: April 2024

The USA has a very significant stock of existing steel buildings that were built before modern design provisions were incorporated into design codes for seismic and hurricane actions. Until about 10 years ago, evaluation and retrofit of structures were based on two documents: (1) ASCE 31 Seismic Evaluation of Existing Buildings, and (2) ASCE 41 Seismic Rehabilitation of Existing Buildings. Over the past decade, efforts have been made to (1) unify the evaluation and retrofit processes into a single document, with the ASCE 41 edition from 2017 mostly completing this task; and, (2) separating loading requirements, to be kept within a new ASCE 41, and material‐specific evaluation/retrofit provisions, to be developed for different construction materials by professional associations. As a result, AISC has recently published ANSI/AISC 342‐22 Seismic Provisions for Evaluation and Retrofit of Existing Structural Steel Buildings to supplement the 2023 edition of ASCE

41. This document applies to metal buildings, particularly steel ones but includes composite, cast iron, and wrought iron elements. To aid in this task, a new edition of the AISC Design Guide 15: Assessment and Repair of Structural Steel in Existing Buildings will be published soon. The paper and presentation will first give some context for the development of the Provisions, and then discuss significant changes, including, to name a few: (1) updates to the condition assessment process and its testing requirement; (2) conditions under which default material properties can be used; (3) factors for expected material yield/ultimate strength for different eras; (4) definitions of simplified force‐deformation curves for force‐ and deformation‐controlled elements; and (5) performance‐ based design parameters.
Reconstruction of a Ukrainian road bridge by use of 3D printed minimass beams
Authors: Coward Andy , Forsberg Torben
Published: April 2024

Minimass is an open “truss-type” concrete and steel beam which creates stiffness and strength through axial compression and tension. The new technique of 3d concrete printing unlocks the potential of this design by allowing the fabrication of these beams at a fraction of the cost of traditional means: no formwork, minimal steel reinforcement, low carbon. The rural bridge in Ukraine is located in Kherson Oblast. The original span was destroyed during the war. The new bridge deck is designed with prefabricated minimass beams, lattice slab concrete panels between the beams and a cast in-situ top slab. The combined use of printed and in-situ concrete leaves various technical issues to be studied, for example the construction joints shall be designed to ensure 100 years’ service life. The minimass beam structure is estimated to reduce the material quantities and embodied carbon by 40% in this case.

Authors: Fairclough Helen , Gilbert Matthew , Pritchard Tom , Firth Ian , Green Daniel
Published: April 2024

In light of the climate crisis, it is important to be able to evaluate both embodied and operational carbon quickly and accurately to ensure the best overall decisions are made. This contribution will focus on the use of digital design tools to guide the former, by rapidly identifying the unavoidable embodied carbon associated with the construction of bridges. Practical design tools are introduced in web-app form (LayOpt:BRIDGE) and as a plugin to the Rhino/Grasshopper parametric modelling ecosystem (Peregrine), each giving results in just a few seconds. The speed of these methods facilitates exploration of different sites or materials. The results provide an absolute lower bound on the embodied carbon required, allowing evaluation of the extent to which it is theoretically possible for a given development to be advantageous. Additionally, the benchmark results obtained can be used both qualitatively and quantitatively to inform proposed designs.
Additive Manufacturing Techniques for Repairable Braced Frames
Authors: Farhoud Hamdy , Mantawy Islam M.
Published: April 2024

Special concentrically braced frames (SCBFs) have been used in lateral load-resisting systems over the last decades. SCBFs are designed to provide significant inelastic deformation capacity primarily through tensile yielding and compression buckling. Even though SCBFs satisfy design requirements for life safety, they sustain high levels of damage which results in economic losses due to the need for replacement. This paper proposes a new concept that focuses on concentrating the damage due to tensile yielding and inelastic buckling in a segment of the brace (fuse) while protecting the rest of the brace. This concept enables repairability after high-level seismic excitation by replacing the damaged fuse. The replaceable/recycled fuses are additively manufactured to achieve desired ductility through optimised geometry. The paper includes a description of numerical results from a small-scale specimen tested under cyclic protocol load.
Preliminary tests for application of carbon nanotubes and Bacillus sphaericus bacteria in self-healing cement mortars
Authors: Goldmann Eryk , Górski Marcin , Klemczak Barbara , Ziembińska-Buczyńska Aleksandra
Published: April 2024

Self-healing in concrete is a popular and developing topic, which utilizes both biotic and abiotic mechanisms to close micro-cracks. Nano additives such as carbon nanotubes (CNT) improve the cement material’s resistance to cracks but could also influence the survivability of microorganisms in concrete. A combination of CNT and calcium carbonate precipitating bacteria might lead to both improvement of concrete’s durability and provide self-healing properties, while increasing the survivability of the microorganisms in the environment of the cement-based material. The presented research focuses on preliminary tests of the influence of the Bacillus sphaericus bacteria and low addition of CNT on the cement mortar’s strength and survivability of microorganisms in the environment of cement matrix. Strength tests and biotic control were performed to provide data to modify the mix for further tests concerning mechanical properties and survival of microorganisms.

Published: April 2024

This paper contributes to the understanding and prediction of the corrosion condition of steel in reinforced concrete structures while proposing solutions to reduce both financial and ecological costs associated with their maintenance. It presents a comprehensive tool and methodology for predicting maintenance and repair in maritime structures and bridges that are exposed to carbonation and chloride ingress. The tool incorporates various resources, including numerical and analytic models, as well as an experimental results database based on existing literature. This database facilitates the conversion of composition parameters into input parameters for the durability models. The application of this tool is demonstrated on a maritime structure in this paper. Deterministic and probabilistic predictions using the Monte Carlo method are utilized to determine the optimal time for inspection and maintenance operations.

Authors: Yvette Sunga Alyssa , Abubakri Shahriar , Lomboy Gilson , Mantawy Islam , Kennedy Danielle , Watts Benjamin
Published: April 2024

This paper presents electric curing of concrete as an effective thermal application method, facilitating the continuous construction of concrete structures during cold weather. Concrete specimens were cast and cured at -15°C for 48 hours, followed by air curing at 20°C. Voltage was applied to the specimens at an early stage to maintain their temperature above the freezing point for the initial 48 hours after mixing while stored at -15°C. The compressive strength of specimens was measured at a 7-day age. Results show that electric curing can linearly increase the temperature of conductive concrete. Additionally, it is demonstrated that a temperature controller can be used to maintain the concrete temperature at a desired level (target temperature) throughout the curing period. The study concludes that electric curing effectively prevents frost damage in conductive concrete, even at temperatures as low as -15°C.
Effect of Column Studs on Column-Pile Joints in Buildings without Underground Beams
Authors: Watanabe Keisuke
Published: April 2024

Column-pile joints without underground beams are becoming a de-facto standard for foundation structures of over-track buildings. In the current design guideline, steel column-pile joints are constructed by embedding the steel column at the top of a cast-in-place concrete pile, and the joint is reinforced by an outer steel pipe. If the joint is to retain seismic performance of the joint with a thinner steel pipe, it will need more reinforcement in the form of studs along the sides of the column and reinforcing bars. Loading tests were conducted with specimens to evaluate performance of the column-pile joint. Specimens with thinner steel pipes and without column studs show smaller strength. However, specimens with column studs and reinforcing bars show greater strength than specimens with thicker steel pipes. From the findings of the experiments above, column-pile joints with thinner outer steel pipes and column studs would seem to be most effective.

Published: April 2024

There are great advantages in adopting steel structure for tall residential buildings. In order to study the mechanical properties of the flat vertical-diaphragm stiffened concrete-filled SHS column joints, such as stiffness, bearing capacity, failure mode, and deformation capacity, full-scale tests and finite element analysis are conducted based on the actual case in China. Results of cyclic tests are listed in this paper. Proper design suggestions and a scientific foundation are provided to the application of this kind of joints accordingly. The test results show that the failure mode of specimen FCFST-S- H is ductile failure due to connection loss and the failure mode of specimen FCFST-C-H is observed as connection failure. In both sets of cyclic loading tests, the joint has good energy dissipation capacity. The finite element analysis results are consistent with the test results.

Authors: Rettinger Martin , Moissiadis Sofia , Hückler Alex , Schlaich Mike
Published: April 2024

Modularity plays a key role in the rationalisation of industrially produced consumer goods and the optimisation of their fabrication technologies. With reduced numbers of individual components, rationalisation, automation, and digitalisation of involved processes become more feasible, and reduction of material quantities and process waste can be achieved. The user further benefits from the possibility of replacement and repair of damaged components as well as disassembly and reuse of components at the end of life. To transfer these benefits to loadbearing engineering structures, the authors propose a modular product family for footbridges using precast segmental technology with dry joints and external CFRP post-tensioning. This article describes the applied principles and benefits of modularity, the modular footbridge design and the influence of dry joints and external CFRP post-tensioning on the bridge’s overall structural performance.

Published: April 2024

The multi-petal tower is a favorable alternative type for supertall buildings because of its distinctive appearance and high wind-resistant performance. The coupling trusses are the important member to connect tower petals to form a stable structural system. The selection of its location and material distribution are of great research value. In this paper, the characteristics and application scenarios of various sensitivity analysis methods are compared. And the incremental sensitivity analysis method is selected to assist determining about the optimal arrangement of the coupling trusses of multi-petal tower under the wind stiffness constraint quickly and efficiently. Based on the sensitivity rank of each coupling truss, the cross section of coupling trusses is optimized. The structural cost of coupling trusses is effectively reduced at the cost of tiny stiffness reduction, which provides an efficient and simple optimization method and application case for similar engineering optimization needs.

Published: April 2024

Seismic reinforcement for steel members employing carbon fiber reinforced plastic (CFRP) bonding, which has been recently implemented in the repair and reinforcement of steel structures, can be expected. However, no examples exist wherein the superstructure is seismically reinforced using CFRP. Therefore, the author's group intends to perform tension loading tests, compression loading tests, and cyclic loading tests to examine the suitability of the CFRP bonding technique as a seismic strengthening method for axial members with H-shaped or rectangular cross sections in steel truss and arch bridges. In this paper, the outcomes of monotonic compression loading tests for H-shaped column specimens, with a focal point on local buckling, is presented.
Experimental and numerical study on the seismic performance of irregularly concrete-filled steel tube column to steel beam joints with inner semi-diaphragm
Authors: Liu Wang-Hui , Guo Yan-Lin
Published: April 2024

This paper studies a new kind of irregular-shaped concrete-filled steel tube column to H-shaped steel beam joints with inner semi-diaphragm (ICFSTC-Joint), which exhibits excellent seismic performance, bearing capacity and stiffness in the engineering structures. Firstly, the experiments of four ICFSTC-Joint specimens under cyclic loading are carried out to investigate their hysteretic behavior and failure mode. It is found that the axial compressive ratio has significant negative influence on the hysteretic behavior of ICFSTC-Joint. Secondly, the finite element (FE) models of ICFSTC-Joint are established and verified by the experimental results. The hysteretic curves and skeleton curves of FE model are obtained and agree well with the experimental results. Thirdly, a parameter analysis on the size of diaphragm is carried out by using established FE model. This paper can provide guidance for the engineering design of CFST column to beam joints under earthquake.
Shake Table Studies of Precast Bridge Columns with a Novel UHPC Connection
Authors: Gao Jianfeng , Li Jianzhong , Ma Biao
Published: April 2024

A novel lap splice connection by ultrahigh-performance concrete (UHPC) was proposed to connect bridge columns with footings. The bond strength between UHPC and reinforcement was quantified by the genetic programming-orthogonal least squares tool. Then, an approach was advanced to guide the design of the proposed connection. Further, a 1/3.5 geometrically scaled bridge specimen was designed and tested on shake tables to validate the effectiveness of this connection designed by the proposed approach and to analyze seismic responses of the specimen. Test results revealed that the precast columns damaged in a flexural pattern reached a drift of 3.2% under the peak ground acceleration of 1.4 g. Moreover, most inelastic deformation and damage occurred above the column-footing connection segments which, designed by the proposed approach, remained barely damaged. Meanwhile, the strain concentration effect at the column bottom was less significant.
M5 Exe and Exminster Viaducts - Strengthening and Safeguarding
Authors: Stroscio Riccardo , Malik Akram , Turlier Frédéric , Maynard Mark
Published: April 2024

Exe (692m long) and Exminster (302m long) Viaducts were built in 1977 and carry the M5 motorway across the Exe Valley in the UK. The deck of both bridges consists of a pair of constant-depth twin- cell post-tensioned box girders with fully external prestressing tendons. In 2016, corrosion was observed in the end-span tendons of Exe Viaduct. A safeguarding solution was proposed comprising additional external post-tensioning. In addition, an assessment revealed that the superstructure did not have sufficient ultimate capacity in the mid-span regions. The assessment of Exminster Viaduct found a similar shortfall in resistance. This resulted in a scheme comprising of external unbonded tendon safeguarding in the end spans of Exe Viaduct and internal bonded tendon strengthening in all midspan regions for both bridges. The solution offered a positive environmental impact avoiding the need for demolition and deck replacement for these two significant motorway bridges.

Authors: Candeias Miguel , Zanon Riccardo , Berthellemy Jacques
Published: April 2024

Tied-arch bridges consist in aesthetic crafted structures with efficient design, providing opportunities for cost reduction and increased sustainability when compared to other bridge configurations. One particular hanger solution, designed by Jacques Berthellemy and implemented typically in radial tied-arch bridge configurations, involves a cruciform element with a variable cross- section along its axis. In this paper the main advantages of using this type of hangers are presented and an assessment is shown regarding the response of this unique hanger under wind loading, an aspect that is not fully addressed within the scope of the simplified approach prescribed by the European standards. The outcome shows that the hanger geometry combines an optimised structural behaviour with an efficient performance, not susceptible to significant vibration risks arising from vortex shedding phenomena.

Published: April 2024

Research in recent years has provided much information about the overall composition and function of the gut microbiota. It has been established that the microbiota contributes to maintaining the integrity of the mucosa, providing nutrients, protecting against pathogens, etc. In addition, the interaction between the microbiota and the mucosal immune system is crucial for the formation of adequate immunity. Thus, understanding the human microbiota can be directed towards better diagnosis and rational treatment of many human diseases. The use of probiotics in various nosological forms demonstrate encouraging results. Diseases of the gastroenterological profile and not only often require the appointment of probiotics. The main mechanisms underlying the beneficial effects of probiotics are considered from the standpoint of their pleiotropic action. The choice of multi-strain probiotic preparations is preferable and justified from the point of view of the synergy of its constituent microorganisms, which allows achieving the best effect. The latest generation of probiotics with an innovative protective double shell demonstrate high clinical efficacy due to the preservation of the viability of probiotic microorganisms in the gastrointestinal tract.

The Concept of the Goodly Life ( Ḥayāt Ṭayyiba ) in the Works of Kenan Rifā‘ī
Authors: Güldütuna Hatice Dilek , Kayahan Nazli
Published: April 2024

Abstract: As one of the most important and influential personalities in twentieth-century Turkish Sufi history, Kenan Rifā‘ī (1867–1950) produced numerous written works and cultivated generations of students until his death in 1950. Despite not writing a dedicated work of either Qur’ānic exegesis ( tafsīr ) or commentary on Prophetic narrations ( aḥadīth ), his recorded discourses and commentaries on other Sufi works, especially on the Masnavī-ye Ma‘navī (Spiritual Couplets) of Jalāl al-Dīn Muḥammad Rūmī (d. 1273 CE), provide a rich source of insight into his thoughts on Sufism and Muslim scripture. This article examines Kenan Rifā‘ī’s understanding of one major Qur’ānic concept, namely that of the goodly life ( ḥayāt ṭayyiba ). Mentioned in Qur’ān 16:97, ḥayāt ṭayyiba , along with its constituent elements of life ( ḥayā ) and goodness ( ṭayyib ), have been the subject of numerous interpretations in premodern Islamic religious and Sufi literature, all of which influenced Rifā‘ī’s own conception of ḥayāt ṭayyiba . To better understand the unique status of the goodly life in Kenan Rifā‘ī’s Sufi teaching, this article examines the use of this term both in his works as well as in the broader literary, semantic, and scriptural contexts that deeply influenced his approach to Sufism. This article is divided into four sections. Beginning with a brief biographical sketch of Kenan Rifā‘ī’s life and career as a Sufi sheikh, this is followed by an analysis of the two constitutive terms of the goodly life ( ḥayāt ṭayyiba ), namely the Arabic terms ḥayā (life) and ṭayyib (good), including their appearances in the Qur’ān and Hadith and their interpretation in premodern Islamic religious literatures. This article then includes a brief section on premodern interpretations of the specific term ḥayāt ṭayyiba before a more extensive examination of how this term is used in Kenan Rifā‘ī’s own writings and oral discourses.

Cross layered adaptive rate optimized irregular LDPC for WSN
Authors: T. Sasikala
Published: April 2024

This paper proposes a cross layered adaptive rate optimized technique that uses irregular low-density parity-check (LDPC) codes over an additive white Gaussian noise (AWGN) channel in wireless sensor networks (WSNs). Irregular LDPC is used as error control code. Cross layer design along with error control code gives the energy balance in the network. This new algorithm uses the physical layer parameters such as coherence time of the channel, BER and SNR and the routing layer parameter such as demanded data rate to determine the rate of the LDPC coder. The algorithm adaptively changes the code rates as ¾, ½, and 1/3. We have conducted the simulations to verify our methods using MATLAB and find that the proposed scheme increases the network performance in terms of energy balance and quality of data by using irregular LDPC codes in the cross-layer environment.
Ankle arthrodesis in Awka, Nigeria: Indications and treatment with unlocked retrograde intramedullary nailing and other methods
Authors: A.C Nwachukwu
Published: April 2024

introduction: Ankle arthrodesis is a key treatment for severe osteoarthritis, often preceding ankle arthroplasty. Nonsurgical options include lifestyle adjustments and NSAIDs, while surgical options range from debridement to arthrodesis. In Nigeria, ankle arthroplasty availability is limited, making arthrodesis the primary solution. Various techniques exist, with open and arthroscopic approaches yielding successful outcomes but varying in complexity and recovery. This study investigates the prevalence, treatment methods, and outcomes of ankle arthrodesis in Awka, Southeast Nigeria. Methodology: The study, conducted in an Orthopaedic Hospital in Awka, Southeast Nigeria, was a prospective cohort study spanning five years (2017-2022). It included 33 patients with various ankle pathologies screened for suitability of ORIF or arthrodesis. Surgeries were conducted under aseptic conditions, utilizing unlocked retrograde intramedullary nails, a dynamic compression plate, and an external fixator. Patients maintained non-weight bearing until radiological union, with implants removed based on individual patient preference and informed consent. Results: Thirty-three patients requiring ankle surgery, with a mean age of 41.44 years were seen between 2017 and 2021. The causes of ankle pathologies included road accidents being the predominant cause (45.5%). The treatment methods were ORIF with intramedullary nails, dynamic compression plates and screws, and an external fixator. ORIF with intramedullary nails was the most common (57.6%). There were 8 subjects who needed ankle arthrodesis, with a mean age of 54.0 years. The prevalence rate was found to be 24.2%. The failure rate was 12.5%. Conclusion: Ankle arthrodesis proves pivotal for severe osteoarthritis, especially in regions with limited ankle arthroplasty access like Nigeria. The prevalence of arthrodesis is 24.5%. Intramedullary nails are very effective in achieving union. Compression plates and external fixators show good results. The failure rate of fixations was 12.5%.

Currently, there has been enormous increase in the use of herbal medicines attributable to their readily availability, affordability, efficacy and good safety profile. This study evaluated the blood boosting potentials of combined administration of Vigna unguiculata and Citrus limon in rat models. Wister rats (135 – 140 g) were used and Vigna unguiculata and Citrus limon were extracted in ethanol. Apart from some preliminary tests, hematology studies were done using standard methods. The parameters tested included red blood cells (RBCs), hemoglobin (Hb), Packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) using hematological analyzer (DxH 560 AL). In the RBC test, combination of Vigna unguculata and Citrus limon recorded a count of 8.07 ± 0.20 x 10-6 on day 15 of treatment. This was highest when compared with the individual administrations which attained 4.04 ± 0.18 and 3.57 ± 0.07 x 10-6 respectively. The combination treatment approached that of the normal control which had RBC count of 8.29 ± 0.13 x10-6. This trend was applicable to other tested parameters. In conclusion, V. unguiculata and C. limon had blood boosting potentials which was more remarkable in the group treated with combination of the two herbs and this was attributed to their phytochemicals such as iron, protein and citric acid as well as their synergistic herb-herb interaction.

Purpose: To review the short term performance 4.5/5.0mm Wise-Lock Narrow Dynamic Compression Plate with LC under cuts and 4.5/5.0mm Wise-Lock Broad Dynamic Compression Plate with LC under cuts for femur fractures in terms of postoperative complications and failure rates. Methods: The total number of 46 patients, 24 to 55 years’ age group, who underwent internal fixation with wise-lock narrow and broad dynamic compression plate for femur fractures were reviewed. These implants were manufactured at Auxein Medical Private Limited Sonipat (India). The wise-lock narrow dynamic compression plates were implanted to 24 patients (18 Male and 05 Female) and broad dynamic compression plates were implanted to 22 patients (15 Male and 08 Female). These plates were made up of SS 316L and Ti6Al4V alloy respectively. Clinical and radiological follow-ups were conducted at the end of 30 days, 90 days, 180 days, 270 days and 365 days after surgery to examine the bone union, non-union & other related complications. During the one year of follow-up by the surgeon the patient's health status was analysed by the American society of anesthesiologists grade and the visual analogue score (VAS) was also determined. Results: Patients were followed up for one year. Out of 24 patients who were treated with wise-lock narrow dynamic compression plate, stainless steel, 04 patients (03 males & 01 female) were faced the complications of pain. However, out of 22 patients who were treated with broad dynamic compression plate, titanium, 02 patients (02 males) developed complications of pain. No biomechanical issue related to screw loosening, corrosion, bending, or other factors was not detected in 46 patients. Conclusions: Femur plate fixation is feasible for the treatment of femur fracture. The clinical outcomes and prognosis of patients are dependent on the accuracy of intraoperative reduction and surgical expertise.
