Abstract
In this paper, the finite element analysis software ABAQUS is used to study the seismic performance of the joints of rectangular steel tubular columns filled with steel-reinforced concrete and H-shaped steel beam in different beam strengths, which are under the same axial compression ratio of 0.2. By the finite element simulation, we can get the load-displacement curves and skeleton curves from the end of H-shaped steel beam. According to the curves and dates, the seismic performance of the joints is analyzed. The shape of each restoring force curves presents for full square spindle, reflecting that the beam-column structure can effectively absorb the seismic energy; with the enhancement of H-shaped steel beam’s strength, the ultimate bearing capacity of the structure is gradually increasing, however, the stiffness and overall stability of the components become worse by degrees; the change of ductility property about the joints is not obvious, showing good seismic performance.
