[摘要] 对下沉式广场带来的结构设计问题进行了分析，分别提出了相应的对策和措施。针对上部结构存在的极弱连接及错层，通过设置防震缝，将复杂的、抗震不利的结构，划分为相对简单、抗震较有利的结构，提高了工程的抗震性能。另外，对美术馆、文化馆主体部分的抗震概念设计及结构超长处理作了介绍。

Abstract: The structural design issue of sunken plaza was discussed, and solution to handling these issues was provided. Due to very weak connections and split-level for the superstructure, seisnuc joints were set to divide this complex and unfavorable seismic resistant structure into individual simple structures to enhance seisrmc resistance performance of this project. For Art Museum and main part of Cultural Center, the seismic concept design and long structure handling method were discussed as well.
