鲁-台经贸会展中心超限工程抗震设计

鲁台经贸会展中心主体采用框架-剪力墙结构,包括展览区、商业区、共享大厅等多个功能区。各功能区通过蒙皮网壳连接形成整体。钢结构与混凝土结构相互交错,涉及的钢结构有桁架、单层网壳、双层网壳等多种形式。整体结构是一个复杂的超限工程。采用基于性能的设计方法,对重要构件提出专门的性能目标。对展厅大跨度楼层钢结构进行了活荷载不利布置分析。重视钢结构的稳定设计,通过多种构造措施和计算分析保证了钢结构的整体稳定。对整体结构进行了动力弹塑性分析,考察了结构的塑性发展程度和变形能力,并对薄弱构件进行了加强。设计结果表明,结构抗震性能良好,结构体系安全可行。

Seismic design on Shandong-Taiwan Exhibition Center object in Weifang city

The frame-shear wall structure was adopted in Shandong-Taiwan Exhibition Center in Weifang city,which includes exhibition areas,commercial areas,public hall,and other functional areas.All functional areas are covered under latticed skin shell.The steel structures include the steel truss,single-layer shell and double-layer shell.The structure is complicated beyond the scope of Chinese Code for seismic design of buildings.Using performance-based design method,the performance objectives of the important compon...
