为了满足多元化、信息化社会发展的要求,以及受土地资源等因素的制约,高层和超高层建筑越来越多,并且建筑功能呈现多元化,当多功能综合大楼要求一幢建筑物的上部、中部和下部使用功能不同时,结构布置也要相应改变,要设置转换构件衔接上下结构,传递内力,设置转换构件的楼层称为转换层。由于转换结构竖向构件的不连续性,上部荷载必须通过转换层的内力重分配才能将上部荷载传递给下部结构的竖向构件,竖向刚度和结构传力途径在转换层及其附近发生了突变,在地震作用下容易产生薄弱部位,因此,转换层构件在整个建筑结构中非常重要并且非常复杂,必须把握好整体功能与局部设计相统一的原则,把握好转换层的概念设计和施工过程的施工质量控制。
In order to meet the requirements of a diversified and informative society and constrained by land resources and other factors, more and more high-rise and super-tall buildings are present, and diversified architectural functions. When the multi-purpose complex requires the upper part of a building, , The central and lower use of different functions, the structural layout should be changed accordingly, to set the transition member convergence up and down the structure, transfer internal forces, set the conversion member of the floor called the conversion layer. Due to the discontinuity of the vertical members of the conversion structure, the upper load must be redistributed by the internal forces of the conversion layer to transmit the upper loads to the vertical members of the lower structure. The vertical stiffness and the structure of the force transmission occur in and around the transfer layer Mutation, prone to weak parts under the earthquake, so the conversion layer components in the entire building structure is very important and very complex, we must grasp the overall function and the principle of local design unity, to grasp the conceptual design of the conversion layer and the construction process Construction quality control.
