摘　　要：东营会展中心展馆结构采用管桁架+塔架拉索结构体系,上覆PTFE膜材;由于建筑功能要求不设缝,展馆钢屋盖长度达360m,层2钢筋混凝土结构长度达189m,属严重超长结构;会议中心采用车辐式索桁架结构,钢索的张拉工艺采用位移控制法。对上述设计中的关键技术进行了介绍,供类似工程参考。The steel pipe trusses covered by PTFE membranes with cable-stayed towers are adopted in order to meet the demand for the architectural style.The total length of the steel roof is up to 360m and the length of the reinforced concrete structure in the second floor is up to 189m due to the limit of the architectural function which demands that seams mustn t be set,which means that it is a over long structure.The rung-shape cable truss structure is used for the center and the tension of the steels is achieved b...
