Аннотация (краткое описание)

The article considers the issues of the construction of high-rise monolithic buildings in Almaty. High-rise construction has received significant development in the territory of the metropolis - more than several dozen buildings more than 20 stories high have been built. Experimental studies of the proper dynamic characteristics of high-rise buildings (periods and forms of natural oscillations, oscillation decrement) and verification of the correctness of the calculation assumptions adopted during their design are relevant. The influence of height on the proper dynamic characteristics of high-rise monolithic buildings constructed in Almaty is analyzed. Data are provided on determining the dynamic characteristics of a 22-storey monolithic building using the building pull-out method with the subsequent abrupt release of the applied load. The results are compared with the data on the proper dynamic characteristics of four high-rise buildings (more than 20 stories high) obtained as a result of vibration tests: - 25- storey Kazakhstan Hotel; - 35-storey building on Al Farabi Street (Nurly-Tau district); - 22-storey building of the Stolichny Tsentr residential complex; -26- storey building of the residential complex "Megatowers". The results of the work can be used in the design of high-rise monolithic buildings.

Практическое значение

The practical significance of this study lies in the determination and analysis of the dynamic characteristics of high-rise monolithic buildings constructed in Almaty under seismic conditions. The obtained experimental data on natural vibration periods, mode shapes, and damping decrement make it possible to verify and refine the design assumptions adopted in structural calculations. The comparison of the test results for several high-rise buildings contributes to improving the reliability and safety of structural design, especially for buildings located in earthquake-prone regions. The research findings can be applied in the design, assessment, and optimization of high-rise monolithic buildings, as well as in the development of recommendations for seismic-resistant construction in Almaty and similar urban areas.
