Abstract:In this study, the influence of design parameters on the anti-collapse capability of a high-rise prefabricated steel structure building was studied. By using ABAQUS finite element software, a low-cycle repeated loading test of the prefabricated concrete plane frame was simulated. The results showed that increasing the axial compression ratio of the frame column can improve the bearing capacity of the structure, and the bearing will decrease rapidly after the peak load is reached. Under cyclic loading, the ductility, bearing capacity, and energy consumption of the structure increased with a decrease in the beam-to-column linear stiffness ratio. With increasing beam-to-column linear stiffness ratio, the distribution uniformity of the story drift ratio worsened; moreover, because of the low-cycle repeated load, the concrete strength will greatly increase, and the energy consumption and ductility will reduce, while the structure bearing capacity will slightly increase. Increasing the axial compression ratio will greatly increase the possibility of the limit state of the structure performance under the same ground motion. A large axial compression ratio of the structure is likely to damage the seismic response performance.
