一、概况 1.1 几种高层建筑结构体系结构体系与施工技术有着密切的关系,因此,了解结构体系对采取何种施工方法有很大的裨益。目前,在高层建筑中,应用较多的有五种: (1) 框架体系:这是施工技术人员所熟悉的一种结构形式,在多层和高层建筑中经常遇到。但框架结构还是属于柔性结构物,它用于抗衡水平荷载的刚度和强度都较低,抗震性能也较差。这从我国唐山震害中可以看出,框架结构上部摇摆度大,建筑物是由上而下地开展裂缝,以至于丧失使用价值。而刚度大的无梁楼盖仅在柱子根部受到
I. INTRODUCTION 1.1 Several types of high-rise building structural system and construction technology are closely related. Therefore, it is of great benefit to understand what kind of construction methods are used by the structural system. At present, in high-rise buildings, there are five types of applications: (1) Frame System: This is a form of construction familiar to construction technicians and often encountered in multi-storey and high-rise buildings. However, the frame structure is still a flexible structure, and it is used to counterbalance horizontal loads with low stiffness and strength, and poor seismic performance. This can be seen from the earthquake damage in Tangshan, China. The upper part of the frame structure is oscillating, and the building is cracked from top to bottom so that the use value is lost. The stiff beamless floor cover is only received at the base of the column.
