［摘要］盛泽文化中心项目为平面不规则、连体结构，通过温度伸缩兼防震缝的设置，将本工程分为几个比较独立的结构单元。针对本工程B区平面严重不规则的情况，采用了平面桁架增强其各部分的连接，减小连接板的在水平地震荷载下的应力；针对A区连体结构且存在大悬挑的情况，进行了多软件的比较分析、弹性时程分析、弹塑性静力分析、重要节点有限元分析以及提高重要结构构件的抗震等级和抗震性能化目标，实践证明本工程在采取相应抗震措施后结构具有充分的抗震能力。

Abstract: Shengze Cultural Center is an irregular plane and connected structure. Expansion joints and anti-seismic joints are designed to divide the structure into several independent structural units. Considering seriously irregular plane structure in area B of this project, plane trusses are used to strengthen connection between various parts and to reduce the stress of connecting plates under horizontal seismic load. Considering connected structure and large cantilever structure in area A, comparative analysis with multiple software, elastic time history analysis, pushover analysis, and finite element analysis of important nodes and improvement of anti-seismic grade and anti-seismic performance of important structural components are conducted. Practice has proved that the structure has great anti-seismic capability after anti-seismic measures have been taken.

Keywords: connected structure; node analysis; anti-seismic measure; plane truss
