摘　　要：简要介绍太仓超高连体双塔的结构布置和超限情况。并针对该工程超限情况及平面不足,提出结构设计中采取的加强措施。并采用两个不同程序对其抗震性能进行计算,计算结果表明主要指标均满足现行规范和规程的要求。最后对其转换桁架和钢骨混凝土柱的节点进行了有限元分析,结果显示节点在不利荷载组合下始终处于弹性工作状态。The structural layout and the information beyond the scope of design codes of a super-high conjined twin towers in Taicang, Jiangsu, were introduced. On the basis of this information, the reinforcing measures of structural design were given. Furthermore, two programs were chosen to seismic behavior. And the results showed that the main index could meet the design codes and specification. Finally, the finite element analysis of the mechanical behavior of a key joint between transfer truss and steel reinforced concrete column was carried out. It was reinforcing its found that the joint was in elastic state under some unfavorable load cases.
