Introduction. Modular buildings currently have a wide geography of application. Due to their advantages, one of the areas of their application in the Russian Federation is the construction of modular buildings in hard-to-reach regions, which are often seismic. Modular buildings are in high demand for industrial facilities, for example, for gas and oil refineries: control and operator buildings, complete transformer substations and switchgear buildings, gas boiler houses, pumping and sewage stations. Such structures require justification of their reliability and compliance with design standards, including seismic ones. At the same time, the standards both in general for modular buildings and in particular for their seismic resistance is poorly developed. Therefore, studying the issue of using modular buildings in seismic regions is a relevant topic. Aim. The purpose of this paper is to study and analyze existing experimental studies of modular buildings and joints for seismic impacts. Materials and methods. Tests of full-size modules and buildings are carried out in Russia and abroad. Accelerogram tests and tests of impacts corresponding to earthquake standards show a fairly high level of seismic resistance of modular buildings, up to the estimated seismicity of 9 points. Studies of joints for cyclic loads demonstrate a fairly high ability of nodes to dissipate energy, which leads to a decrease in the reaction under seismic impact. damping coefficients in the considered studies lie within 0.2 ÷ 0.3, which is close to reinforced concrete structures. At the same time, various dampers in nodes can be used to increase the seismic resistance of a modular building. Discussion. Modular buildings have a wide geography of construction, including seismic regions. Certification and laboratory tests of full-size modules and buildings show their high level of earthquake resistance, up to an estimated seismicity of 9 points. Intramodule assemblies also have high dissipative properties, while various dampers can be used to increase earthquake resistance. Used Books:
