Description
技术领域technical field

Cost; the lateral deformation of the steel column is constrained by the concrete, and the force is reasonable.
框架节点是水平、竖向构件的结合部，是楼、屋面荷载传递的关键部位，也是框架结构中最薄弱、最易受损的部位之一。节点及其附近区域在地震作用下承受较大的内力，为实现“强节点弱构件”、“强剪弱弯”的抗震设计理念和要求，通常在这些区域需布置致密的钢筋，导致节点处钢筋冲突严重。目前采用的实腹钢柱节点形式中开孔工作繁多，施工难度大，难以保证钢筋工程的质量，增加验收工作的难度。The frame node is the joint of the horizontal and vertical components, it is the key part of the load transfer of the building and the roof, and it is also one of the weakest and most vulnerable parts in the frame structure. The joints and their surrounding areas bear large internal forces under the action of earthquakes. In order to realize the seismic design concept and requirements of "strong joints and weak members" and "strong shearing and weak bending", dense steel bars are usually arranged in these areas, resulting in Rebar conflict is serious. The current form of solid-web steel column joints has a lot of opening work, and the construction is difficult.
