Performance Analysis of Key Joints and Seismic Design of High-rise Structures

Abstract

The structural layout and the information beyond the scope of design codes of a double-tower-connected superhigh structure were introduced. On the basis of this information, the stiffening measures of structural design were given. Furthermore, two programs are chosen to study the seismic behavior. And the results show that the main index can meet the design codes and specification. Finally, the finite element analysis of the mechanical behavior of one key joint was carried out. It can be found that the joint is elastic under some unfavorable load cases. Therefore, the joint is safe.
