In order to study the seismic performance of H-shaped SRC column under bidirectional horizontal loading,the fiber model is used to simulate the existing tests,and the simulation results applicability the correctness of the model. Based on this model,the effects of axial compression ratio,steel ratio and steel strength on the bearing capacity,energy dissipation and ductility of H-shaped SRC column under bidirectional horizontal loading are investigated,and compared with those under unidirectional horizontal loading. The results show that the axial compression ratio has a significant influence on the seismic performance of H-shaped SRC column. As the axial compression ratio increases,the bearing capacity of the column first increases and then decreases,while the energy dissipation and ductility gradually decrease with the increase of the axial compression ratio;The steel ratio has a certain influence on the seismic performance of H-shaped SRC column,and the The bearing capacity,energy dissipation and ductility of the column increase obviously with the increase of the steel ratio;The bearing capacity,energy dissipation and ductility are all improved slightly with the increase of steel strength. In addition,the bearing capacity,energy dissipation and ductility of the SRC column under bidirectional loading are lower than those under unidirectional horizontal loading.
