目前,在国内外的一些高层建筑设计中.为了保证结构物在水平侧力作用下的稳定性,往往将楼梯间或电梯间做成井筒型式(图1),并将其视为一主要抗侧力构件,以承担全部或绝大部分水平力,从而使框架体系从侧力影响作用下解脱出来,使其主要承担垂直荷载。这种功能上的分工,不但使框架节点的处理简单,便于施工;并且为改革结构体系,即将传统的粱板柱体系改为板柱体系,创造了条件。在我公司承担施工的劲松小区框架轻板试验楼工程设计之初,我公司曾会同清华大学建工系在天津市某框架 At present, in the design of high-rise buildings at home and abroad, in order to ensure the stability of the structure under the action of the horizontal lateral force, the stairwell or the elevator room is often made into the wellbore type (Figure 1), and it is regarded as a main anti-side The force component is used to bear all or most of the horizontal forces, so that the framework system is released from the influence of the lateral force and it is mainly responsible for the vertical load. This functional division of labor not only makes the processing of the framework nodes simple and facilitates construction, but also creates the conditions for the reform of the structural system, that is, the change of the traditional fascia board system to the plate column system. At the beginning of the engineering design of the Jinsong Community Framework Light Board Test House under construction undertaken by our company, our company has worked with Tsinghua University to build a system in a framework in Tianjin City.
