static elastoplasticity;  failure correlation;  System reliability;  Frame structure

In building structure, system reliability is an important indicator to measure the overall performance of the structure. In the calculation of system reliability, an urgent problem to be solved is the problem of correlation between structural components or sections. Based on the static elastoplastic method, the failure correlation of reinforced concrete multi-layer frame structure under small and large earthquake conditions was studied, and the partial failure correlation law of frame beams and columns under small and large earthquakes was obtained.
