摘要
保利国际广场是一体型复杂的高层建筑,在3层设置巨型转换桁架来支承上部楼层,结构施工对结构成型有很大的影响,通过施工模拟分析及对比,确定巨型桁架的施工顺序、支撑架的拆除时间及楼板后浇带的浇筑时间,对楼板裂缝进行有效的控制,最后进行了施工健康监测,并与计算结果进行对比。
The Poly International Plaza is a high-rise building with an unusual shape,mega-truss with supporting for upper structure was setted in 3 floor. The construction of mega-truss has a great influence on the structure forming. Depending on construction simulation analysis,the construction sequence of the mega-truss,the dismantling time of the false work and the pouring time of the floor slab were determined,the floor crack was effective controlled. At last,the calculation results by the method of construction health monitoring was compared.
