某高层建筑采用核心筒-外框筒体系,核心筒由包含钢板剪力墙的混凝土剪力墙构成,外框筒由巨柱、重力柱、大斜撑、转换桁架构成。鉴于外框筒的巨柱施工到一定阶段,单根巨柱在高空中分叉为两根,开发了一种用于外框巨柱施工的可拼装钢连桥,以方便施工人员在分叉巨柱焊接过程中进行操作。通过合理的构造设计,钢连桥能够实现快速拼装和增加桥体长度。用有限元软件计算校核钢连桥的应力和变形,以满足强度和刚度要求。
A high-rise building uses the core tube - the outer frame tube system, the core tube by the shear wall containing steel shear walls constitute the wall, the outer cylinder by the giant columns, gravity columns, large bracing, conversion truss structure. In view of the outer cylinder of the huge column construction to a certain stage, a single column in the high-altitude bifurcation of two, developed a framework for the construction of a huge pillar can be assembled steel bridge in order to facilitate the construction staff in the bifurcation Pillar welding operation. Through rational design, the steel bridge can be quickly assembled and increase the length of the bridge. The finite element software is used to calculate and verify the stress and deformation of the steel continuous bridge to meet the strength and stiffness requirements.
