Abstract
This paper describes about the early detection of chronicity foot lesion in diabetic patients by monitoring their foot pressure. Patients with diabetic for long term and poor glycemic control are often leads to peripheral neurovascular disorder. This neurovascular disorder is caused due to Diabetes Triopathy (inadequate levels of growth factors & presence of biofilm). This neurovascular complication results in foot ulceration. 40% to 50% of diabetic patients are affected by foot ulceration. These ulceration leads to lower extremity exclusion even in the absence of critical branch ischemia. So, early detection and prevention of foot ulcer is needed. In this paper, hardware is setup to monitor the foot pressure in diabetic patients continuously with the help of flexi force sensor. For effective screening of foot ulceration, a graphical program environment LABVIEW is used. In this work, foot ulcer is detected earlier. So that it can be prevented earlier. Normalized PeakPressure (KPa)values are listed based on collected performa and had classified the diabetic patients and normal patients.
New method for testing the sedimentation stability of modern concretes at construction sites
Authors: Gecgel A S , Baumert C , Garrecht H 
Published: October 2019

Abstract
Modern concretes are characterised not only by rising demands on properties but also by increasingly complex compositions. With sophisticated formworks and dense reinforcements, the trend in concrete technology continues towards to self-compacting and easily-compacting concretes. The use of highly effective superplasticizers makes these concretes not only more efficient but also more susceptible to environmental factors and influences. Compliance with desirable fresh and hardened concrete properties is becoming increasingly problematic. In this case, there are no methods for testing today’s concretes, especially the easily-compacting and self-compacting concretes, which are suitable for construction sites. Because of their sensitivity, however, these should be examined separately for their tendency to segregation and, in this context, for their sedimentation stability. For this reason, a test method is currently being developed at the Institute of Construction Materials at the University of Stuttgart, which is intended to examine concretes in particular for this problem. First preliminary test in a simplified procedure have already confirmed the basic idea of testing.

Authors: Kusumawardaningsih Y , Fehling E , Hardjasaputra H , Al-Ani Y , Aboubakr A A M 
Published: October 2019

Abstract
UHPC and UHPFRC are remarkable materials which have properties with significant advantages. In addition to high compressive strength, they have higher tensile strength than conventional concrete. To study the tensile strength of UHPC and UHPFRC, a series of experimental programs have been developed at Kassel University. The effects on the fibre efficiency produced by varying the volume of the steel fibre percentage are discussed. When the results are compared to proposed equations generated in some European countries, the results are generally similar and confirmed satisfactorily. Satisfying justifications are also obtained when applied to the results for the axial tensile strength of the UHPFRC specimens. By using the proposed equations, the fibre’s effective (efficiency) stresses in UHPFRC in the stages of fibre activation and pullout can be calculated. However, not all the results of this study can be confirmed by other countries (e.g. USA, Japan). Diverse circumstances taking place during the production of the material may have to be taken into account to explain the dissimilar output. Studies of the tensile strength of UHPC and UHPFRC are important, with the aim of supporting more documentation for the development of recommendations, guidelines, standards and norms; thus meeting the needs of structural design.

Abstract
Industrial revolution is a series of events driven by the growth of technological innovations, and so far, the world had witnessed the first three industrial revolutions. Today, a new revolution referred to as the fourth industrial revolution is entering even though it is still in its early stages of development. Many developed countries had established their own roadmap or strategic plan as a first step. However, only a few of them touched the construction sector even though the construction industry provides a significant contribution to the country’s GDP. Based on this understanding, there is a fundamental need to give a clear view of Industry 3.0 to Industry 4.0 from the construction industry’s perspective, since most users are still finding their way in this transition. An extensive literature review is used to define the scope and terms of the field of construction in the industrial revolution. Towards this goal, a clear definition and concept of each revolution, key technologies related to construction and challenges faced by the industry will be explored. Simultaneously, this review paper also benchmarked a few documents as a simple guide in the transition process to the fourth industrial revolution to avoid a lag in a world where changes are swift and sudden. Therefore, this review paper contributes by providing a better understanding of the challenges and trends in Construction 4.0 to academics and practitioners. Moreover, it will spark new ideas on the policy or strategic roadmap development in the future.
A case study of slope hazardous mitigation by ground monitoring system
Authors: Yang B H , Lai J , Cheng C F 
Published: October 2019

Abstract
The western foothills geological zone of Taiwan contains sedimentary rocks such as conglomerate, sandstone, shale, and mudstone. These formations often cause severe damage to life and property during a natural disaster such as earthquake and rainstorm, especially on a dip slope. This paper presents the results of long-term ground monitoring on a high sliding potential dip slope located in the western foothills of central Taiwan. The slope has been went through substantial movements induced by rainstorms during the monsoon season or after a typhoon. By comparing the rainfall data and long-term in-situ measurement of ground displacement using total station and inclinometer, we find that the movement of this slope is highly related to regional rainfall. The slide mechanism can be attributed to the infiltration of rainfall that tends to increase the driving force of the upper sliding mass and decrease shear resistance on the interface between sandstone and shale.

Published: October 2019

Abstract
Structural failure, which can be caused by design miscalculation or changes in the building’s function, can be dangerous if left untreated. Consequently, structural strengthening is done by providing steel plates, fiber-reinforced-polymer, or in the traditional way using bamboo fibers. In this study, a numerical calculation for bamboo strengthening using the FEM method is conducted. Bamboo strengthening was installed on concrete beams and attached using mortar. The analysis was carried out with ATENA software dealing with beam specimens, namely Control Beam (BC) and Bamboo-strengthened Beam using M13 and M20 mortar (BB13 and BB20). The materials used are CC3DNonLinCementitious2 and CCD3DBiLinearSteelVonMises for concrete and bamboo, respectively. The concrete and mortar use the fracture concept of a uniaxial stress-strain law and the constitutive model of the bamboo is based on a linear stress-strain law. The results of comparing the numerical and experimental results for the load-carrying capacity ratio are 0.96, 0.90, 0.77 for BC, BB13, and BB20, respectively. The crack pattern of the specimens shows that collapse is by flexural cracking starting from the mid-span. This is in accordance with previous laboratory results. In conclusion, the analyses using ATENA program and experimental methods show the appropriate results.

Published: October 2019

Abstract
Structural strengthening with Carbon Fibre Reinforced Polymer (CFRP) confinement has been widely used in civil engineering applications. However, the use of CFRP has always triggered environmental and sustainable issues due to its hazardous manufacturing and disposal process. By using partial CFRP confinement, the use of CFRP as the strengthening material could be reduced. The circular hollow reinforced concrete column is commonly used in seismic zones due to its self-weight reduction and better structural efficiency of strength/mass and stiffness/mass ratios properties. However, up until today, the understanding of circular hollow reinforced concrete column behaviour still lacks, especially with CFRP partial strengthening confinement. Therefore, this paper is testing a 6 full-scale circular hollow reinforced concrete columns with 2 m height, 250 mm of outer diameter, and 110 mm of inner diameter. The behaviour of the unconfined circular hollow column will be compared with partial CFRP confinement under axial load. The circular hollow reinforced concrete column with partial CFRP confinement is proven to be able to strengthen circular hollow column effectively through this study.
Tracing developing deterioration zones in a damaged dam by using elastic wave tomography

Published: October 2019

Abstract
In this paper, the concrete gravity dam built 40 years ago was partially damaged by the M=7.3 Chi-Chi Earthquake in central Taiwan in 1999. The elastic wave tomography method was applied to identify the safety conditions of the repaired dam in 2010. The resulting velocity profiles showed that the total structure conditions were accepted as a good to questionable condition. The filled materials and cracks existed in some dam components. Seven years later, the updating tracing investigation revealed that the pervious detrimental zones were spatially extended and associated with time. These testing results were also consistent with the findings from the ground penetrating radar inspection.
Strength calculation method of reinforced concrete structures of Tashkent underground tunnels with different stages of stress condition
Authors: Miralimov M 
Published: October 2019

Abstract
Modern requirements of engineering practice in tunnel construction are related to the problems of strength and the identification of reserves of bearing capacity of tunnel lining. The achieved success in creating rational reinforced concrete structures of tunnel linings is largely determined by the results obtained in the field of mathematical and mechanical modeling of deformation processes. Reinforced concrete large-sized building structures constitute the main structural elements of the Tashkent underground tunnels in Uzbekistan, as reinforced concrete under proper conditions gives a significant technical and economic effect, reducing the time and cost of construction. Experiments on the bending of reinforced concrete beams with a gradually increasing load indicate various stages of the stress condition. To achieve the most economical consumption of materials, it is proposed to calculate structures for the forces that act under breaking load. This paper presents a method for calculating the lining of reinforced concrete tunnels of the Tashkent underground based on the more accurate assessment of the fundamental properties of reinforced concrete that determine its behavior under external load.
Applications of hysteretic steel dampers for controlling the seismic damage in steel frames
Authors: Teruna D R 
Published: October 2019

Abstract
The aim of seismic design is not intended to make earthquake-proof structures that will not experience any damage even during a strong earthquake; such structures will be too costly. However, controlling the damage to the desired level is a necessity for buildings with a particular purpose such as hospital, fire and police station, nuclear facilities, buildings that contain hazardous material, and other building that is critical for emergencies and defense. In this paper, a four-story steel frame, both with and without hysteretic steel damper are investigated in order to account the effect of stiffness ratio, and SR (ratio between steel damper and braces stiffness to the bare frame stiffness) in the global structural damage. For these purposes, three ground motions which are compatible to the design spectrum response in the Indonesian building code were selected to be applied to the structure with a stiffness ratio (SR) of 2, 3, 4 and 5 using a non-linear dynamic time history analysis. In this context, the damage index based on the works of Park and Ang is used as the criteria to define global structural damage, while story drift index is used as the criteria to measure the seismic performance level. The results demonstrated that the use of steel damper not only enhances the seismic performance, but it also reduces the damage index of the investigated structure. Furthermore, the damage index and story drift index are influenced by the stiffness ratio, in which the stiffness ratio of 4 (four) provides the smallest damage index and inter-story drift index. Moreover, the damage index and inter-story drift index were also affected by ground motions characteristics.

Abstract
Concrete damage (cracks, voids and delamination) significantly influence initiation and propagation phase of reinforcement corrosion. The three methods are combined in the framework of this research: (i) on-site testing on concrete bridges, (ii) application of an advanced numerical model for service life prediction on existing structures and (iii) laboratory experiments on permeability of cracked concrete. The aim of this research is to determine the mutual interaction of material, structural, environmental and climate performance indicators under following degradation mechanisms: chloride induced corrosion of reinforcement in concrete and concrete cracking due to mechanical and non-mechanical loading. The broader aim is to predict bridge service life more precisely as a base for establishment of an optimal bridge quality control plan. The focus of the paper is application of on-site testing on existing bridges. Influence of cracks in concrete on reinforcement corrosion on existing structures can be determined by application of non-destructive testing, not only by measured values but also to define area of structure on which a crack has impact.
Treatment of uncertainties in green engineering
Authors: Schwarte J , Hein H L 
Published: October 2019

Abstract
Uncertainties occurring in engineering are usually dealt with by means of statistical validation. Most value assignments are of statistical nature and thus only valid in a specific statistical way. This fact is, in most cases, only implicitly apparent but nevertheless almost always present. In green engineering this is not true. The calculation e.g. of life cycle assessments (LCAs) is generally based on a vast number of values. These data either cannot be validated in a statistical sense at all or they are too insufficient to be usable for statistical analyses. This means that final results in this field cannot be declared as trustworthy in a way that is common in engineering. In this paper, the method of interval arithmetic is proposed as a way to circumvent this severe epistemological problem. The consequences of the suggested approach are illustrated utilizing two typical examples: (1) Different reliabilities concerning theories for greenhouse effect influences of various chemical emissions on the greenhouse effect and thus on the global warming potential and (2) Situations, where one specific production site differs heavily from the average of the dedicated industrial sector. Computational implementation of the considered concept is briefly discussed. It is shown that misleading results, which may be quite common in this field, can possibly be avoided in the proposed way.

Abstract
Cantula Fiber (Roxb Agave Cantula) is a natural fiber that can be developed as a reinforcement material in concrete and can be applied to structural and nonstructural elements of a building. This research aimed to test the direct tensile strength of polymer modified mortar by strengthening cantula fiber in various forms of cantula fiber reinforcement ratios. Test specimens were in the form of polymer modified mortar with reinforced woven fiber and short fiber as textile reinforced concrete (TRC). Specimens used were in the form of plates measuring 12 mm x 80 mm x 400 mm with variations in fiber reinforcement ratios of 1.5%, 2.5%, 3.5%, and 4.5%. Test specimens were tested at age of 3 days and 28 days. The results of the test showed the highest increase in the reinforcement ratio of 4.5% in the PMM specimen with a tensile strength value of 2.41 MPa at 3 days and at 3.41 MPa at 28 days. Meanwhile, the value of the largest tensile strength in TRC was found on the reinforcement ratio of 3.5% with a tensile strength of 2.95 MPa at 3 days and 3.38 MPa at 28 days. Therefore, the effective reinforcement ratio ranged from 3.5% to 4.5%.
