Computational analysis of the stress-strain state,strength and stability of tallest skyscraper of the Moscow international business center with allowance for static and wind loads and hypothetical local damage

摘要

The paper is devoted to the stress-strain state computational analysis,strength and the load-bearing structures stability of a multifunctional high-rise residential building with an underground parking lot,developed by the architect Sergey Skuratov.This object is the tallest skyscraper,located on the territory of the Moscow International Business Center also known as Moscow-City.Static loads,wind loads and hypothetical local damage are taken into account.Brief information about the problems formulations,methodology of structural analysis and corresponding software systems,the building finite element models(including verification issues)and the analysis results are presented.The computational studies results analysis performed with the use of software package ANSYS Mechanical showed a consistent displacements and forces distribution(forces and moments)in the building foundation and frame with allowance for vertical static and wind loads,significant natural frequencies and mode shapes of building.
