［摘要］莫桑比克莫中文化中心由容纳1 500座的大剧场、容纳500座的小剧场及中国文化中心三部分组成，通过设置防震缝将结构划分为三个独立规则的单体，同时合理的设置连廊使三个结构单元成为一个有机的整体。项目地基土湿陷性的特性要求对基础进行特殊处理，采用后注浆端承摩擦桩，同时不考虑湿陷性土层的承载力对基础进行设计，完全消除湿陷性土对主体结构的影响，同时确保结构沉降满足规范要求。大剧场属于大跨度空间结构，通过比选，采用钢桁架结构，同时对支承桁架的框架柱及台口柱等重要构件按照中震弹性的性能目标进行性能化分析，确保结构安全；悬挑楼座根据跨度及边界条件的不同分别采用悬挑梁及悬挑桁架的结构形式，同时对悬挑部分进行舒适度验算，对受力复杂部位进行有限元分析，确保结构的安全，同时达到经济、合理的目标。

Abstract:Sino Mozambique Cultural Center of Mozambique consists of a 1 500-seat grand theatre, a small 500-seat theater and a Chinese cultural center. The structure is divided into three independent rules by setting the anti-vibration joint, and the reasonable corridor setting makes the three structural units an organic whole. The characteristics of the foundation soil collapsibility of the project require special treatment. The post-grouting end bearing friction pile was adopted, and the foundation was designed without considering the bearing capacity of the collapsible soil layer, which completely eliminating the influence of collapsible soil on the main structure. At the same time, which ensure that the structural settlement meets the requirements of the specification. The grand theater is a large-span spatial structure. Through the comparison, the steel truss structure was adopted, and the important components such as the frame column and the pillar column supporting the truss were analyzed according to the performance objectives of the medium-seismic elastic to ensure the structural safety; According to the different span and boundary conditions, the structure of cantilever beam and cantilever truss were adopted. At the same time, the cantilever part was checked for comfort, and the finite element analysis was carried out on the complicated part to ensure the safety of the structure and at the same time achieve economic and reasonable goals.

Keywords:theatre structure; large span open structure; collapsible soil; overhang seats; corridor
