The Time History Analysis of the Frame Structure Component Considering Torsion Component of Earthquake
In this paper, both 一-shaped and L-shaped reinforced concrete frame structures are established in ANSYS, and then，the one-way seismic waves, bi-directional seismic waves and two-way plus torsion seismic wave are respectively input to the both of frame structural model, and carried out the torsion angle displacement analysis. Simulations show that: in both frame structures, the torsion angle of column under multidimensional seismic waves is around 20 % greater than it under the one-way seismic wave and corner column is particularly obvious, so we should considered multi-dimensional effects of the earthquake and pay attention to strengthening corner column in seismic design. And the torsion angle of asymmetric structure and increasing rate of it are about 2% larger than the corresponding symmetry structure. So we should pay attention to the torsion effect of irregular structure.
