PENGARUH VARIASI WAKTU PEMBEBANAN TERHADAP SIFAT REOLOGI VISCO-ELASTIC ASPAL PEN 80/100 DENGAN PENAMBAHAN ASBUTON MURNI
Authors: Alkam Rani Bastari 
Published: May 2022

Abstract: Time Sweep (loading time) is one of the main variables affecting the performance of asphalt related to loading resistance on the road surface. To describe the loading time effect on the viscoelastic properties of asphalt pen 80/100 with varying content of pure Asbuton with dif-ferent time sweeps, the basic rheological characteristics and mechanical rheological properties were measured with a dynamic shear rheometer in the laboratory. Complex shear modulus (G*) decreased, phase angle values increased, and strain value increased with increasing load-ing time. Vehicle speed and loading frequency were inversely proportional to loading time; thus, it can be concluded that increasing the vehicle speed and increasing the vehicle loading frequency will cause an increase in G*, decrease in phase angle, and decrease in strain. Bitu-men stiffness modulus (E *) was inversely proportional to the increase in loading time. Perma-nent deformation damage criteria, both before and after mechanical rheology test (RTFOT), showed that the shorter the loading time, the stronger the bitumen is in resisting permanent de-formation damage. Based on fatigue cracking criteria, all combinations of loading time and Asbuton content fulfill the statutory requirements for fatigue cracking resistance. Abstrak: Waktu pembebanan (Time Sweep) merupakan salah satu variabel utama yang mempengaruhi kinerja material aspal yang berkaitan dengan ketahanan terhadap pembebanan pada perkerasan jalan. Untuk dapat memperoleh gambaran dari pengaruh variasi waktu pem-bebanan terhadap sifat reologi visco-elastic aspal pen 80/100 dan Asbuton murni maka dil-akukan pengujian sifat reologi dasar dan sifat reologi mekanistik dengan alat Dynamic Shear Rheometer dengan beberapa variasi kadar Asbuton murni. Hasil peneitian menunjukkan pen-ingkatan waktu pembebanan menyebabkan penurunan nilai complex shear modulus (G*), pen-ingkatan nilai phase angle, dan peningkatan nilai regangan. Jika hasil ini dikaitkan dengan ke-cepatan kendaraan dan frekuensi pembebanan yang berbanding terbalik dengan waktu pem-bebanan, maka dapat disimpulkan bahwa peningkatan kecepatan kendaraan dan bertambahnya frekuensi pembebanan kendaraan akan menyebabkan peningkatan nilai G*, penurunan nilai phase angle, dan penurunan nilai regangan pada sampel. Dalam tinjauan modulus kekakuan bi-tumen diperoleh peningkatan waktu pembebanan menyebabkan penurunan modulus kekakuan bitumen. Dalam kajian kriteria kerusakan Permanent Deformation baik pada kondisi original maupun pada kondisi setelah RTFOT dapat disimpulkan bahwa semakin kecil waktu pem-bebanan maka semakin kuat bitumen tersebut dalam menahan kerusakan Permanent Defor-mation. Sedangkan, dalam kajian kriteria kerusakan Fatigue Cracking dapat disimpulkan bah-wa seluruh kombinasi waktu pembebanan memenuhi persyaratan jika dilakukan tinjauan ketahanan material terhadap fatigue cracking.

Published: May 2022

Abstract
Induction furnace slag (IFS) and quarry dust (QD) were reported as good materials in making ordinary concrete. Studies were not done on utilizing IFS and QD as constituents of high-performance-self-compacting-concrete (HPSCC). This study aims at assessing the effects of induction furnace slag and quarry dust on the strength and durability of high-performance self-compacting concrete. Strength tests including compressive, flexural, split tensile, rebound hammer tests were conducted on HPSCC. Likewise, durability tests including water absorption, total porosity and electrical resistivity tests were conducted. IFS at 0 % to 50 % (at 10 % intervals) replacement with Portland cement was used. Also, the optimum IFS content was combined with QD at 0 % to 50 % (at 10 % intervals) replacement with river sand. The results revealed an increment in strength up to 20 % IFS, 50 % QD with a rise of 15.34 % compressive strength over the control. The durability improved up to 20 % IFS, 60 % QD with a rise of 16.86 % electrical resistivity over the control. These showed that IFS and QD can be used for the production of HPSCC.

Authors: Bahrami Alireza , Azizian Dawod 
Published: May 2022

Abstract
This study assesses glulam and reinforced concrete (RC) beams in a multi-storey building in Gävle in Sweden. StruSoft FEM-Design software is used to conduct the current study. First, the building having the RC beams is modelled, analysed, and designed. Utilisation ratio, stress, weight, reaction force, stability, and deflection of the building are examined. It is concluded that the building can function well with RC beams. Then, the RC beams are replaced with glulam beams and the building is again analysed. It is revealed that larger cross-sections are needed for the replaced glulam beams in most of the spans compared with the RC beams in order for them to have acceptable results from the utilisation ratio viewpoint. However, for large spans of 8 m, a timber column is used in the mid-span for all the storeys as a strengthening alternative so that a shorter span for these glulam beams can be adopted which leads to acceptable results. Stresses of the RC and glulam beams are also evaluated. The building having the glulam beams is 23.79 % lighter than the building having the RC beams. The maximum reaction force of the building having the glulam beams is obtained 24.27 % lower than the building having the RC beams. Stability and deflection of the building in both cases are discussed as well.

Published: May 2022

Abstract
Currently, structural engineers design structures as fixed bases, ignoring soil-structure interaction (SSI). Due to difficulties in the modelling of soil and the absence of procedure to incorporate effects of SSI in seismic design codes. Various researchers have shown the importance of considering SSI during earthquakes. This paper highlights the interaction effects of SSI, its seismic response, the general procedure for engineers to incorporate the impact of SSI. Various methods to solve SSI problems and their provisions are mentioned in different International Seismic Codes reviewed. However, there is an urgent need to incorporate detailed guidelines considering SSI effects in the Indian Seismic code. Thus, Indian engineers should reach for international Codes or other available literature to solve their SSI assignments.

Authors: Kraľovanec Jakub , Moravčík Martin 
Published: May 2022

Abstract
In recent years, lots of researchers have given attention to prestressing evaluation in existing prestressed concrete structures. In Europe, many existing prestressed concrete bridges are about to reach their limit of service life and exhibit signs of deterioration. Therefore, reliable, and effective methods for determining the actual state of prestressing are needed. Indirect methods represent a valuable tool for the structural assessment of prestressed concrete members in service. These methods include, e.g., Saw-cut method, Structural response method, Barkhausen noise technique, or Wire-cutting method. The presented paper summarises indirect measurements focused on prestressing force monitoring using the aforementioned techniques performed in the Laboratory of Civil Engineering of the University of Žilina.

Published: May 2022

Abstract
In the proposed research there were evaluated the factors influencing the distribution of additional pressure from ground construction on the linings of the subway tunnels. In recent years, the Department of Tunnels and Subways of the Emperor Alexander I St. Petersburg State Transport University has provided scientific support for many capital construction projects with geotechnical calculations of the buildings under construction impact on subway structures, both using analytical methods and mathematical modeling. The existing analytical methods allow us to evaluate the change in the additional pressure in the ground massive without taking into account the tunnel construction, while in reality the tunnel construction significantly changes the stress-strain state of the ground massive in the vicinity of the excavation. This factor was considered as the most significant, and together with it, there were evaluated the influence of the tunneling method and the influence of the applied geomechanical soil model on the calculation results.

Published: May 2022

Abstract
Authors have long been guided by the following premise in their research, educational, professional and publishing activities. Components of the Integrated Transport Infrastructure (ITI) of Slovakia, including roads, should be designed, built, managed, maintained, recycled (decomposed) at a reasonable price, in reasonable quality, respecting the relevant requirements of users, residents and sustainable development throughout life cycle. Elements of ITI Slovakia, as important landscape ecological elements, should be designed with respect to aesthetic principles considering the cultural and natural wealth of Slovakia. Slovak technical universities have recently been criticized for teaching 50-years-old curriculum. The authors dare to disagree with the statement and, due to their scientific profile, pre-sent their partial outputs of a holistic approach to the sustainability of transport structures with a priority focus on pavement. In the intentions of the above mentioned, it could perhaps be partly convergently concluded that they learn new things in the field of transport construction, but under the old names.

Abstract
This paper examined the polyethylene terephthalate (PET) polymer waste effect that using as a partial replacement for fine aggregate on the R.C beams structural behavior. Six replacement percentages by weight were used in this study: 5 %, 7.5 %, 10 %, 12.5 %, 15 %, and 20 %. Seven concrete beam specimens with dimensions of 150 × 300 × 2300 mm were tested, in which one specimen for each PET replacement percentage was added to the reference specimen. four-point load setting were used to test all specimens via failure load, maximum deflection, energy absorption, stiffness, ductility index, flexural strain, first crack load, and crack pattern. Results showed that raising of PET percentage in the concrete beams leads to an increase in failure load, maximum deflection, ductility index, strain, and energy absorption compared with the reference beam in the ranges 0 – 4 %, 23.2 – 93.7 %, 12.13 – 93 %, 432 – 1139 %, and 51.8 – 275.4 %, whereas its causes a decrease in initial stiffness and secant stiffness in the ranges 5.8 – 38.44 % and 19.2 – 46.4 %. Moreover, crack investigations revealed that the load at which the first crack forms raise when the PET waste content increases.

Published: May 2022

Abstract
The total solar energy transmittance (TSET, g - value) is a parameter of transparent system, which can significantly affect the heat demand for cooling of buildings in the summer. A wide range of progressive transparent and shading systems have been developed and applied to a large number of buildings. Their energy performance and efficiency can be determined using simulation tools or measurements. The methodology for accurate g - value determination is described in ISO 19467: 2017. The aim of the study was to derive and verify an alternative methodology for estimating the total solar energy transmittance of selected specimens of transparent systems in case when the standardized equipment is not available or the aim is not to know the exact TSET value. Window specimens were tested under laboratory conditions, which were retrofitted with elements that improve their original properties in terms of heat transfer coefficient and protection against overheating. In total, three methodologies were designed and described, based on A) monitoring of heat fluxes through glazing, B) monitoring of temperature rise in the hotbox and simulation, and C) determination of the difference in heat fluxes of an irradiated specimen and in the absence of radiation. A solar simulator and a heated hotbox were used for the measurements according to the needs of the chosen methodology. The results from the different approaches for determining g - values differ only slightly but are informative. The conclusion from all measurements is the fact that the tested specimens representing type of windows applicable in building retrofitting showed high potential in terms of reducing heat gains from the sun.

Published: May 2022

Abstract
Textile-Reinforced Mortar (TRM) or Textile-Reinforced Concrete (TRC) can produce novel structural techniques in civil engineering fields. The current study experimentally investigated the bending behavior of thin geopolymer mortar panels reinforced with Fiberglass Textile Grids (FGTG). The experimental work totally consisted of twelve panel specimens divided into two groups; each group included six specimens. The first specimen of each group was unreinforced, whereas the rest of the specimens were reinforced with a different number of grids; however, each group’s molarity of NaOH solutions was different. The results showed that the flexural strength and compressive strength of geopolymer mortar were significantly increased with the increment of molarity of NaOH solutions by 33 %. Textile reinforced geopolymer mortar (TRGM) panels showed deflection hardening behavior and multiple cracking. The deflection values at the same load levels were decreased when the number of grids and the molarity of NaOH solutions were increased. For TRGM specimens, in addition, the difference in molarities of NaOH solutions depicted a clear influence on the number and propagation of cracks. The toughness values of TRGM specimens were importantly enhanced with the increase of the FGTG reinforcement ratio.
Effect of Soil Nonlinearity on Analysis of Raft Foundation
Authors: Saeed Haitham H. 
Published: May 2022

Abstract
Soil supporting foundations behave in a nonlinear manner at loading close to its bearing capacity. This behavior affects soil pressure distribution and the corresponding stresses in the raft foundation, which differs significantly from considering the soil as elastic linear material. The present research uses the finite element method to study the effect of soil nonlinearity on the behavior of raft foundations subjected to concentrated loads. The analysis is based on the Winkler type of foundation. The analysis considered different values of the average soil pressure to its bearing capacity. The supporting soil was modeled as elastic perfectly plastic material. The effects of soil nonlinearity on the intensity and distribution of soil pressure, punching shear force, and bending moments in the raft are investigated. The effects of the foundation stiffness evaluation factor L·λ on the behavior of rectangular raft foundations were studied. This parameter combines the effects of the modulus of subgrade reaction, raft thickness, modulus of elasticity of concrete, and column spacing, as these parameters are interrelated. The results indicated that considering the subgrade soil as a linear elastic material underestimates punching shear and bending moments compared to modeling the soil as an elastoplastic material.

Authors: Sorsa Alemineh 
Published: May 2022

Abstract
This study was to evaluate the engineering properties of cement stabilized expansive clay soils. This study considered an experimental program to determine Atterberg limits, free swell index, compaction characteristics, California Bearing Ratio (CBR), and swell of the mixtures. The collected expansive soils were stabilized using 10, 12, 14, and 16 % of cement by weight. The laboratory results showed that the soils have low shear strength and high swelling potential, which indicates the soils are weak for subgrade without improvement. The improvement of some of the engineering properties of expansive soil stabilized by 14 % cement was 15 % for liquid limit, 23 % for plastic limit, 73 % for plasticity index, 9 % for optimum moisture content, 6 % for maximum dry density, 55 % for the free swell index, 1332 % for California Bearing Ratio, and 88 % for swell. The analysis results indicated that 14 % cement stabilization is very effective for the improvement of expansive soil strength.
Tsardom of Muscovy Traditional Culture and Peter's Westernization Project
Authors: Chernikova T. V. 
Published: May 2022

The article studies Peter the Great “revolutionary” westernization project of Russia by reviewing the most significant differences in the socio-cultural system of Russia centuries compared to its Western European counterparts in the second half of the 15th – early 18th century. The first part of the article identifies the distinctive features of the socio-cultural system of Russia, which the observers from the Western European saw as the most different from the “correct” European norms and institutions in the second half of the 15th-16th centuries. The most distinctive feature was the concentration in the hands of the Moscow sovereign not only of the state political power but also the property rights on all the country's resources. It resulted in the development of the public sphere in Russia along the line of “sovereign vs slaves”, which precluded the Renaissance Western political thought “to accept” Russia into “Europe”.The author examines two main Western description of Muscovy (Muscovia) in the 15th – 17th centuries: a benevolent approach adopted by Johannes Fabry, Paolo Giovio, Alberto Campense; and a critical approach taken by most authors analyzing Muscovy (Matvey Mekhovsky, Sigismund Herberstein, etc.). These two approaches were also reflected in the dispute between the jurists of the late 16th century about the legitimacy of the state power in Russia – “illegitimate tyranny” by Herberstein and Fletcher and “legitimate despotism” by Boden. These debates in RenaissanceEurope informed and shaped the concept of the patrimonial monarchy (patrimonial system) in Russia, which was subsequently developed by Russian influential historians (V.O. Klyuchevsky, P.N. Milyukov and others) and foreign experts (R. Pipes, E. Carrer d'Ancausse and others).The second half of the article analyzes the concept of “Europeanization” (“Westernization”) of Russia and offers a periodization of this phenomenon. The start of early Europeanization, when Russia began borrowing military, technical, cultural, and other innovations from Western Europe can be dated from the birth of a unified Moscow state. Peter's Westernization was indeed a new stage in adopting European experience because he removed the state and church barriers in the communication of Russian people with Western Europeans and encouraged not only going to the West for education and science, but also opened the way to the creation of secular education and science in Russia. These were prerequisites for the beginning of the modernization of Russia.In other matters, Peter's westernization differed from the previous periods only in the number of cultural and institutional adoptions. Peter’s political system was the apogee of the patrimonial culture in Russia.
