摘要
对超高层巨型框架结构桁架层下连次柱的施工技术进行介绍。通过在次柱施工过程中采用专门设计的临时支撑系统,合理地安排施工顺序,控制加载程序和实施结构变形监测等一系列手段,保证了上部桁架结构在加载完成之前可自由变形,整个巨型结构体系能够按照设想的分工协作方式进行传力,从而实现了巨型框架结构体系中结构的水平荷载与竖向荷载主要由巨柱和桁架组成的巨型结构承担,次柱只承受本层竖向荷载或者上部传递的少量竖向荷载的目的。
It was focused on a construction technology of super high-rise steel buildings that could make second column be under the truss layer .With a specially designed temporary support system , reasonable arrangements for the construction sequence and a series of measures to control loading procedure and do deformation monitoring , this technology ensured that the upper truss could be freely deformed before the loading was completed , and the entire structure could transfer the force with the envisaged collaborative approach .Horizontal load and vertical load in the mega frame structure are carried primarily by the column and truss of the mega frame structure .Second column only carries vertical loads of the layer or few vertical load transfered by the upper layer .
