高层建筑式立体车库方案设计与静力弹塑性分析

Scheme design and static elastoplastic analysis of high-rise building stereo garage

针对城市中停车困难区域,提出了高层建筑式立体停车方案,并对立体车库进行结构设计。运用PKPM-STS建立了该立体车库的三维模型,使用SATWE计算了该模型在风荷载和地震荷载作用下的楼层位移、层间位移角和层间位移比,分析了该车库结构的变形特性和受力特点。运用MIDAS GEN对该立体车库结构进行了静力弹塑性分析,分析了立体车库结构塑性铰发展的过程、速度以及分布位置,找出结构中薄弱层的位置,来指导设计和施工,以对薄弱层进行加固处理。

Aiming to difficult parking areas in city,high-rise building stereo garage parking schemes were proposed,and structural design of the stereo garage was made.A 3d model of stereo garage was established by PKPM-STS,the layer displacement,interlayer displacement angle and displacement ratio of the model under wind and seismic loads were calculated by SATWE,and the deformation characteristics and force characteristics are analyzed.Further,static elastoplastic analysis was performed on the stereo garage with MIDAS GEN,the development process,speed,and distribution position of the plastic hinges of stereo garage structure was analyzed,the position of the weak layer of the structure was found to guide the design and construction of the weak layer reinforced.
