Nonlinear numerical analysis of SRC-RC transfer columns based on OpenSEES

摘要

In order to study the seismic behavior of SRC-RC transfer column under low-cycle loading, the open source finite element software OpenSEES was used to establish models of SRC-RC transfer column based on fiber model and conduct numerical analysis. Compared with experimental results, numerical analysis results are found to be reasonable and valid. Then the influence of factors such as stirrup ratio and axial-load ratio are contrastively analyzed. The results show that axial-load ratio has a greater influence on the bearing capacity and hysteretic performance of the structure, but the stirrup ratio has less influence.
