Dynamic Response Analysis of Steel Rope Impact on Asymmetric Twin Tower Building with Large Bases

The FEM model of asymmetric twin tower building with large bases was established with FE-program ANSYS. The influences of steel rope on the structural dynamic characteristics were analyzed. The x-direction level seismic excitation were input with the help of time-domain analysis method, the influence of steel rope on the top’s acceleration ,the bottom shear force and bending moment of the structure were researched. Some useful results were obtained.
