    摘要:

    基于对竹子优越力学性能的分析及其相应结构特点的研究,在考虑到垂直升降型立体车库结构与竹子宏观结构形式及荷载形式的相似性后,提出按等稳等侧移的仿竹原则在这类结构适当高度处设“节”,形成带有环箍层的仿竹型筒式钢构架结构,并对仿竹型结构与非仿竹型结构进行静力及稳定性能综合对比分析.结果表明:按此原则布置环箍层的仿竹型结构的抗侧刚度显著提高,层间位移小且均匀,利于升降设备运行;柱内力突变程度相对缓和,结构抗倾覆能力提高;结构整体稳定性由环箍层间等效短柱控制,稳定极限承载能力增强,验证了仿竹型立体停车结构中环箍层布置的合理性.

    Abstract:

    Considering that the structural type and load feature of vertical lifting tridimensional parking structures are similar to those of bamboo, a new structural arrangement style of tridimensional parking structure was presented, that is to set hoop-layers like bamboo knots at their proper height according to the imitating bamboo principle that any two adjacent hoop-layers have equal stability and lateral displacement. The static and stability properties of imitating bamboo structure and non-imitating bamboo structures were studied. It is shown that the lateral stiffness of imitating bamboo structure is obviously improved and the storey relative lateral displacement becomes smaller and more uniformly distributed. The internal force mutation of columns is relatively moderate, and the resisting overturning ability of structures is enhanced. Moreover, the whole stabilization of structures controlled by equivalent short columns improves the stability bearing capacity. All the above verify the rationality of the arrangement of hoop-layers in imitating bamboo parking structure.
