摘　　要：介绍了钢结构屋面的抗侧力体系和竖向支撑体系分离在本工程中的运用及相应的理论分析和构造措施。本工程引入了抗震性能化设计方法,保证关键构件在罕遇地震中处于弹性阶段。通过对整体模型的计算分析,反映了上部钢结构屋盖与下部钢筋混凝土框-剪结构协同工作对位移及受力性能的影响,提出了工程关键技术的处理建议。The application of separation method of lateral resisting system and vertical brace system of the steel roof in the project is presented,including the corresponding theoretical analysis and the constructional measures.Performance -based seismic design method used in the project is to ensure that the stress of the critical components are in flexible stage in the rare earthquake.Through computed analysis of the overall model,the effects of collaborative work of the upper part of the roof steel and the lower part of reinforced - concrete frame - shear wall structure on the displacement and capacity stressed are reflected,the disposals of key technologies of the project are raised.
