Time History Analysis of the Non-Symmetrical Special-Shaped Column Structure on Multi-Dimensional Seismic
In this paper, the spatial analysis model of non-symmetrical special-shaped column is established in ANSYS, and then, the translational and rotational component of the seismic wave was input to the frame structural model, taking account of stiffness enhancement of the floor on the beam, and carried out the elastic-plastic time-history analysis. Simulations show that the trend of development of displacement basically the same way on two horizontal components and torsional acceleration component, and the displacement on two horizontal components and torsional acceleration component increases significantly compared with one horizontal component; because of the presence of the floor, the intensity of beam is enhanced, leading to some columns more strain than the beam, so the floor should be fully considered in the design of the beam.
