Assessment of the load-bearing capacity of materials and structures using a finite element model

Abstract

The current technical condition of a multi-storey frame building structures is studied. The survey is carried out for individual structural elements of the object, which makes it possible to determine the actual technical condition of the building and its constituent elements. Additional damage and defects appeared at the object under study due to the forced break in construction. Verification calculations of the non-existent capacity of structures were performed based on the results of the technical condition monitoring. The existing real operational loads and impacts were taken into account in the calculations for the actual design schemes. The results of field studies were processed to develop a reconstruction project for a frame multi-storey building. Quantitative estimates of the actual quality indicators of load-bearing building structures were used. A computer-based verification calculation based on the application of a finite element model was performed for the construction of a cinema hall located in the frame building under study. Plots of internal forces in structures are obtained. It is concluded that the object under study is in a working technical condition.
