Based on the existing experimental data, a finite model of HDCSW with steel plate concealed bracing under low-cycle load was established reasonably with nonlinear finite element analysis software MSC.Marc. The influence of axial compression, steel ratio, height-width ratio and span-depth ratio on the capacity and deformation performance of HDCSW with steel plate concealed bracing was analyzed systemically. If the axial compression ratio is greater than 0.4, the ductility of HDCSW with steel plate concealed bracing will be obviously decreased. When the relative ratio of the steel plate concealed bracing is between 0.96 and 6.73, it will improve the ultimate bearing capacity of HDCSW with steel plate concealed bracing. The height-width ratio and span-depth ratio have a major effect on the capacity and deformation performance. The research results of HDCSW with steel plate concealed bracings have a certain reference value with elastic-plastic calculation under seismic.
