Abstract
Purpose: The aim of this work is to evaluate the probability of progressive collapse due to the removed column in a basement of the experimental building using three computational methods – quasi-static, dynamic and kinematic methods of the limit equilibrium.
Methodology/approach: The stress-strain state of the semi prefabricated building system is performed by the finite element method using the verified software package Ing+ MicroFe.
Research findings: It is shown that no progressive collapse can occur with the removed column in a basement of the experimental building. A 15 % precision is obtained in comparing calculation results of the progressive collapse by three methods of the limit equilibrium. The dynamic approach provides larger values of the ultimate load than the quasi-static and kinematic approaches.
