摘　　要：广州某会议中心建筑外观造型独特,整体结构复杂。根据结构受力特点,常规跨度楼盖区域采用普通钢筋混凝土构件支承,而跨度较大楼盖区域则采用钢梁+型钢混凝土柱+钢筋桁架楼承板的结构形式。结构整体分析指标表现良好,说明结构布置合理;二层超长楼盖在温度作用组合工况下的应力均未超过混凝土抗拉强度标准值,楼板在正常使用状态下未出现开裂。另外,还补充了项目北侧大跨度弧形钢连廊的构件应力分析、变形验算以及竖向振动舒适度验算,分析结果表明大跨度连廊结构竖向振动舒适度满足要求且具有足够的承载力和刚度。The architectural appearance of a conference center in Guangzhou is unique and the overall structure is complex.According to the structural stress characteristics,the conventional span floor area is supported by ordinary reinforced concrete members,while the larger span floor area is supported by steel beam+reinforced concrete column+reinforced truss floor plate.The performance of the overall struc‐tural analysis index is good,indicating that the structure layout is reasonable;The stress of the overlong floor on the second floor does not exceed the standard value of the tensile strength of concrete under the combined condition of temperature action,and the floor does not crack under normal use.In addition,the stress analysis,deformation checking calculation and vertical vibration comfort calculation of the large-span curved steel corridor on the north side of the project are supplemented.The analysis results show that the vertical vibration com‐fort of the large-span corridor structure meets the requirements of the code and has sufficient bearing capacity and stiffness.
