［摘要］施工顺序会影响复杂结构构件的内力，斜撑与桁架组合转换结构中斜撑水平推力在楼盖中的传递途径是复杂结构设计的关键。研究了光明新区公共服务平台斜撑与桁架组合转换结构在竖向荷载作用下传递斜撑水平推力时转换层楼盖的受力特征；通过对两种施工过程的计算，分析比较了转换层楼板的施工顺序对结构传力途径的影响以及对结构主要受力构件内力的影响。分析结果表明，不同施工方案对楼盖中的梁与板的内力分配有一定的影响，尤其在斜撑水平推力较大时楼盖的内力变化更为明显，若处理不当会存在较大的安全隐患。

Abstract: For complex structures, construction sequence directly affects component’s internal force. The transmission way of inclined support’s horizontal forces in the floor is the key point in design of inclined support and truss combined transfer structure. Mechanics characteristics of the transfer floor of Guangming New District public service platform under inclined support transfer structure’s horizontal forces were studied. Comparing the calculations of two different schemes of construction process, influence of construction sequence of the transfer floor on key components’ internal forces and horizontal force’s transmission way was studied. The results show that construction process scheme has certain effect on the force distribution way in beams and slabs. This affection is more obvious when inclined support’s horizontal forces are large and the great hidden danger would appear if it’s inappropriately managed.

Keywords: inclined support and truss combined transfer structure; large-span arch-transfer structure; transfer floor; construction sequence
