【 摘 要 】

Based on the structural analysis software ANSYS, a three-dimensional dynamic analysis model of frame structure with specially shaped columns is established. The influence of ratio of section height to section thickness on the seismic performance of the frame structure with specially shaped columns is studied, and the relative ratio of section height to section thickness is determined. On the basis of ratio of section height to section thickness, the energy dissipation properties and failure mechanism of frame structure with the specially shaped columns under the rare earthquake are studied. The results show that the ratio of section height to section thickness has a certain influence on the seismic performance of the structure, and seismic performance of the structure is better when the ratio is close to 4.
