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
