摘要
广交会展馆四期扩建工程项目展厅的钢结构屋盖由珠江散步道、标准展厅和卡车通道组成。为了满足业主对标准展厅跨度及净高的功能要求,对5种钢结构屋盖的结构体系进行比选,最终采用了下弦设置穿心式预应力钢绞线的倒三角形立体桁架的结构体系。对所采用的结构体系的基本设计信息进行介绍,并对其进行了荷载分析、施工模拟分析及屋盖抗连续倒塌分析。结果表明所采用的结构方案在满足业主需求的情况下是安全可靠且经济合理的,各项指标均满足规范要求。
The steel structure roof of exhibition hall in part IV expansion project of Canton Fair Complex is composed of Pearl River Walkway,standard exhibition hall and truck passage.In order to meet the functional requirements of the owner for the span and clear height of the standard exhibition hall,the structural systems of five kinds of steel structure roofs were compared and selected.Finally,the structural system of the inverted triangular three-dimensional truss with the bottom chord set with the piercing prestressed steel bar was adopted.The basic design information of the adopted structural system was introduced,and the load analysis,construction simulation analysis and roof progressive collapse resistance analysis were carried out.The results show that the adopted structural scheme is safe,reliable and economical under the condition of meeting the needs of the owners,and all the indexes meet the requirements of the specification.
