The Time History Analysis of the Frame Structure with Special-Shaped Columns Considering Torsional Component of the Earthquake
This paper is concerned with the study on internal forces of structure by building model in ANSYS under unidirectional seismic wave, bi-directional seismic waves and two-way and reverse seismic wave. The results revealed that the moment effect of frame structure under bi-directional seismic waves and two-way and reverse seismic wave is bigger around 30% than it under unidirectional seismic wave. And the torque accretion multiple of irregular structure is bigger around 1 than the corresponding regular structure. Therefore, we should take into account the effect of multi-dimensional seismic and the torsional effect of the irregular structure in structure design.
