某在建高层建筑框架柱节点拆除支撑方案设计

The design of support project in dismantling the frame structure joints of an abuilding tall building

某在建高层建筑由于施工问题造成其中一楼层部分框架节点混凝土强度达不到设计要求,经各方研究决定拆除节点区混凝土,由于该楼层上部已施工有五层,必须采取临时支撑措施,确保上部结构的安全,本文对支撑方案的计算、构造、实施及节点区混凝土的恢复进行了总结,供同行参考。

In an abuilding tall building, because of the construction reason, some frame structure joints in a floor whose concrete intensity didnt satisfy the design demand. These joints had to be dismantled. But there were five floors had been constructed, so it should take temporary support to assure the safe of structure. This article sums up the computing, construction and building of the support project and introduced the recover of the joint＇s concrete. It can provide some references to structure engineers.
