Abstract:The theater-commercial district in Jingjiang Cultural Center adopts frame-shear wall structure. Its form is very irregular and does not have clear “floor” concept. The whole structure belongs to a spatial mechanical system of steel-concrete mixed structure. The theater-commercial district mainly includes three parts: the large-span steel truss, the theater and the free-form steel roof. Firstly, the structural types, spatial relations and connection modes of each part were introduced in detail. Secondly, according to the characteristics of the project, the calculation model, load value and damping ratio were briefly introduced, and the seismic performance-based design method was adopted to distinguish the key parts, key components and common vertical components, and energy-dissipated components. The seismic performance target of key components was designed. Then the section steel braced steel plate shear wall system in mega-concrete tube was introduced emphatically, as well as some calculation measures and step-by-step construction measures to prevent wall cracks. Finally, the basic design of the project and the dynamic elastic-plastic analysis of the whole structure under three-dimensional rare earthquakes were briefly described.
Keywords:spatial mechanical system of mixed structure; section steel braced steel plate shear wall system; mega box-shaped pile cap
