Abstract
The newly-built 20-story hospital building is located in the seismic fortification 8 degree area, and its independent steel corridor is a steel frame structure. In order to analyze the performance of the structure under strong earthquake, the static and dynamic elastoplastic three-dimensional finite element model of the structure is established by using the finite element software PERFORM-3D. In this paper, buckling restrained braces are used for energy dissipation. Through the dynamic elastic-plastic analysis of the steel frame buckling restrained brace structure, the structural response under strong earthquake input is analyzed, and the structural reliability is checked.
