The Internal Force Analysis of Special-shaped Column Frame Structures in Different Forms under the Action of Multidimensional Seism

摘要

Two three dimensional models were set up using ANSYS finite element analysis software, different seismic waves (unidirectional horizontal seismic action, bidirectional horizontal seismic action, bi-directional horizontal seismic action and torsional component seismic action) were input into the regular and irregular special-shaped column framework structures, and then nonlinear computation was done. The paper analyzes the aseismatic capability of the framework structure with special-shaped columns by comparing the bearing condition of different components of different structures under seismic wave, which would provide instructions for the aseismatic design of the framework structure with special-shaped columns.
