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。
Lutai Economic and Trade Convention and Exhibition Center main frame-shear wall structure, including the exhibition area, business district, shared lobby and other functional areas. Each functional area is connected by a skin net shell to form a whole. Steel and concrete structures are intertwined, involving steel truss, single-layer reticulated shell, double-layer reticulated shell and other forms. The overall structure is a complex overrun project. Adopting a performance-based design approach that sets specific performance goals for critical components. The unfavorable placement analysis of live load was carried out on the steel structure of large span floor of exhibition hall. Emphasis on the stability of the steel structure design, through a variety of structural measures and calculations to ensure the overall stability of the steel structure. The whole structure was analyzed by dynamic elasto-plastic analysis, the degree of plasticity development and deformation capacity of the structure were investigated, and the weak components were strengthened. The design results show that the seismic performance of the structure is good and the structural system is safe and feasible.
