摘要:

大跨预应力混凝土楼盖结构形式多种多样,不同的楼盖结构,需要选择不同受力性能的结构形式.以郑州国际会展中心展览部分大跨预应力混凝土楼盖为研究对象,分别讨论了主次梁结构、次梁承重结构以及井字梁结构3种结构形式5种不同的结构布置方式,并对其进行了分析计算.针对各结构布置方案的受力特点,通过对5种不同布置方式的预应力筋用量、结构内力以及变形的分析,结果表明,对于此类双向跨度相差不大的结构,井字梁方案较优.该结论为正确选择结构布置方案,优化楼盖结构方案提供依据.

Abstract:

There are various forms of large-span prestressed concrete building structures, and different building cover structures need to choose structural forms with different stress properties. Taking the large-span prestressed concrete building cover of the exhibition part of Zhengzhou International Convention and Exhibition Center as the research object, three structural forms and five different structural arrangements of primary and secondary beam structure, secondary beam load-bearing structure and tic-tac-toe beam structure were discussed, and they were analyzed and calculated. According to the force characteristics of each structural layout scheme, through the analysis of the amount of prestressed ribs, internal force and deformation of five different arrangement methods, the results show that the tic-tac-toe beam scheme is superior for such structures with little difference in bidirectional span. This conclusion provides a basis for the correct selection of structural layout scheme and optimization of building structure scheme.
