摘要
以邯郸客运中心主楼为工程背景,针对本工程存在的6层高位大跨度连体结构,采用顶层钢桁架+预应力拉索结构型式。由于连体结构形式的复杂性,对结构进行施工全过程模拟分析,重点介绍了结构施工顺序以及预应力拉索的张拉方案,分析了拉索张拉过程中结构内力的变化情况,为类似大跨度连体结构的合理设计和施工提供参考。
Based on the engineering background of the main tower of Handan central transport station, which has six floors high and long span connected structure system, we choose the top steel truss ＋ prestressed cable structure form. Due to the complexity of the connected structure, the whole construction process of simulation analysis is taken. Especially, Paper introduces the sequence of structure construction and the tensioning solution of prestressed cable. The change of the structure internal forces while cable tensioning process is also analyzed.The results provide a reasonable basis for the design and construction of long-span steel connected structures.
