摘　　要：在当前的工程建设中,预应力钢结构以其技术先进、经济合理、安全适用,应用前景广阔。本文利用有限元分析软件SAP2000研究对比了预应力巨型支撑-钢框架结构与纯钢框架结构、巨型支撑-钢框架结构的抗侧移性能;从集中荷载模式和均布荷载模式两方面对预应力巨型支撑-钢框架结构的侧移模式进行了分析;并运用数值模拟手段研究了支撑的预应力与结构抗侧刚度的关系等关键问题,并得出了相应的结论,可为预应力巨型支撑-钢框架结构的设计和加固提供一些参考依据。At present, prestressed steel structure has wide application prospects in the construction, which with advanced technique, reasonable economy, safety and applicable. Based on FEA software -- SAP2000, lateral resistance performance of prestressed-mega- brace-steel frame structure, steel frame structure and mega-brace-steel frame structure are contrasted. Under the concentrated load and uniform load, lateral displacement mode of prestressed-mega-brace-steel frame structure is analyzed; and the relation between brace＇ s prestress and lateral stiffness of structure are studied with numerical simulation method, and the corresponding conclusions are derived, which could be used to provide some references of design and reinforcement for the prestressed-mega-brace-steel frame structure.
