[提要]  北京展览馆综合楼展示中心采用了框架剪力墙-空间钢桁架结构体系，对这种新型的空间结构形式采
用了不同程序进行对比分析计算。分别采用了刚性和弹性楼板假定，并考虑了垂直地震作用、温度应力对结构内力与变形的影响，验算了罕遇地震作用下结构的弹塑性变形。对影响结构抗震性能的关键节点进行了抗震设计，为混合结构在高烈度区的应用积累了经验。

Abstract:  Frame shear wall-space steel truss structure system is adopted in Beijing exhibition center building. Different procedures are adopted to calculate and analyze the new style space structure.The influences of rigid and elastic floor slab assumtion, vertical earthquake action and the temperature stress on the structural internal force and deformation are analyzed. The  structural elastic-plastic deformation under infrequent earthquake is checked. The details of seismic design for key joints  that affect structure seismic capability are carried out. The designuorks accumulate experience for the applications of hybrid structure at high intensity regions.
Keywords: steel-reinforced concrete mixted structure; frame shear wall-space steel truss; seismic design; rigid or elastic slab assumtion; temperature stress; joint construction
