Abstract:
The investigation results revealed how modified standard Portland cement of grade 42,5 (M400) with 10% of the expanding additive changes the deformation characteristics of heavy concrete.Heavy concrete of class B 22.5 (M300) with a different water-cement ratio (slump 3 cm and 5 cm) was selected as the object of study, from which cubic specimens of side 10 cm were prepared.The impact of modified cement on concrete linear deformations is determined at the ages of 1, 3, and 28 days under normal setting conditions, and changes in the sizes of the same specimens are checked for three months under air-drying conditions.The study confirmed that the most effective impact of modified cement, as in the case of construction mortars, is also observed in 3–7 days of curing. It was found that the effect of modified cement is increased with the increase in the water-cement ratio, and a relatively low percentage of expansion through the low water-cement ratio is explained by the certain rigidity of the concrete internal structure.

Abstract:
The geodetic monitoring results of the earthquake in the seismically active area at the Republic of Armenia using GNSS technologies are presented in this article. The necessity of using geodetic tools-equipment, in particular satellite technologies, in the process of seismic studies is substantiated, proving the fact of the validity and reliability of the data. The monitoring results of the horizontal-vertical shifts’ coordinates of the permanent reference stations affected by the earthquake in Armenia on February 13, 2021 at different time intervals (5 days before the earthquake, 2 hours and 10 minutes before and after, as well as at the moment of the earthquake) were analyzed and the graph analyzes were given.

Abstract:
The study of a development length determination according to Armenian and foreign building standards is presented. For analysis implementation different concrete classes (B20, B25, B30) and rebar diameters (25mm, 28mm, 32mm) were chosen. Reinforcement bar class A500C was taken. Two different cases were considered: in one case, the reinforcement is taken in tension, in the other case, in compression. The calculation results were presented graphically using the "Wolfram Mathematica" software package. The results are shown that in the cases of both tension and compression, the value of the anchorage length obtained by Armenian building standards is 23.1% more than by Russian codes received. In the case of tension, the value of the anchorage length obtained by American codes is 16.7-20.8% more than the one obtained by the Armenian building standards.

Abstract:
Currently, Sedati Regency's coastal region has undergone an identity shift. The region, which was once renowned as a representation of seaside culture, has been changed into a new official residential community. the beginning of new operations in 2018, such as the massive construction of formal settlement sites. In an effort to establish a new identity, each of these operations maintained control over coastal regions. By employing power relations analysis approaches, such as archeology and genealogy, to uncover local behavior, which in turn can establish regional identity, qualitative research techniques and data analysis can be used. According to Focault's analysis, the identity of the coastal region is changing, and the local Javanese and Madurese cultures are having an impact on the power dynamics in informal dwellings. Meanwhile, because the majority of inhabitants are diverse immigrants, power dynamics in formal housing are shaped by urban culture.

Abstract:
Today, people are increasingly drifting away from nature in an age of accelerated lives and information technology. Only the natural environment can create comfortable, ecological conditions for human life. It has become evident that the biological component of the domain has been noticeably reduced in the big cities, and the appeal to the global architectural community of the ecological and aesthetic aspects of design and construction, which contribute to the comfortable and sustainable development of urban space, has become particularly relevant over the past decades. In a big city, architecture is omnipresent. Hence, the architectural-spatial environment should be solved as much as possible in the context of the natural environment, embodying not only the material needs of a person but also spiritual ones. The current unfavorable environmental, energy, and economic situation in the world requires new methods for designing and building the architecture of new and reconstructed old buildings. The article discusses the issues surrounding the formation of modern energy-efficient architecture in the context of its relationship with the natural environment through the use of modern design solutions. The article is based on surveys of social facilities made by the authors from 2017 to 2021 in Eurasian and European cities. The article analyzes a new mechanism of architectural formation based on the shape formation of an architectural object, the content of the architectural shape, the aesthetics of perception, and the organization of eco-space.

Abstract:
The paper aims to apply such principles of territorial planning in border areas and regions under the threat of war, which will allow to meet the primary needs of the population under relatively peaceful conditions and, in emergency situations, will reduce the vulnerability of territories and populations. To solve this problem, the issues specific to the border regions and principles of their classification were studied, which were found both in international documents and in scientific publications. In the example of the Meghri community of Syunik Marz, RA, such factors directly related to spatial planning, such as geographical location; natural, economic, and cultural resources; territorial placement of settlements; population; and infrastructure, were investigated. To solve the problem of access to public services, the infrastructures for providing the primary needs of the population were selected and categorized according to access levels. The study's findings led to recommendations for using these spatial planning concepts, which will guarantee that all the residents in the community's settlements have access to services.

Abstract:
The dependence of energy dissipation coefficient on filtration properties and on creep characteristics of soil skeleton is examined. The study was carried out on the basis of the general solution of the joint task of creep and consolidation theory for a two-phase soil system obtained on the basis of the generalized model of bulk forces, taking into account the interaction of soil phases, changes over time in the general stress state at any point of the soil and additional pressures in pore water, and incomplete transfer of external pressure to the pore water. Interactions between phases are taken into account in the solution of the one-dimensional joint task of the theory of creep and consolidation, and the creep kernel is taken in the form of an exponential function. The formula for the deformation of two-phase soils is presented as the sum of two syllables due to primary and secondary consolidation of the soil. The strain formula uses experimentally obtained values of filtration characteristics and creep parameters of the soil skeleton. Using the formulas obtained, hysteresis loops under sinusoidal stress changes can be plotted and the energy expended per deformation cycle and the dissipation coefficient for two-phase soil can be obtained.

Abstract:
The main objective of the article is to assess the stress-strain state of building structures under seismic action taking into account the dynamic characteristics of the soils. As well as an assessment of the effectiveness of strengthening method of masonry building based on the Time History Analysis of the bearing capacity of structures.During the study a real existing masonry building is chosen. The building is modeled with the Lira-SAPR computer software with usage of the proposed strengthening method. Then, with the help of full-scale tests, the geophysical characteristics have been determined, as well as the prevailing period of the soil. Based on the existing engineering-geological and obtained by us geophysical data, the synthetic accelerogram corresponding to the masonry building soils have been chosen. The Time History Analysis of the building structures under seismic action have been carried out using previously obtained accelerogram, where the results have been compared with the standard Response Spectral method. And, finally, based on a comparison of various methods for assessing the bearing capacity, the effectiveness of building strengthening has been evaluated. The results of this study can assist the structural engineer in making better decisions for future design decisions.
