Description
技术领域technical field
本发明涉及一种钢结构梁柱滑动连接节点，属于工程技术领域。The invention relates to a beam-column sliding connection node of a steel structure, which belongs to the technical field of engineering.
背景技术Background technique
对于一些大跨度或者柔性结构，其在地震作用或温度作用下往往会产生较大的变形，当需要释放这种结构变形时，一般在结构的适当部位设置滑动支座。如果这种滑动连接设置于钢结构非顶层梁柱节点区域时，通常是在柱身相应位置增设牛腿，在牛腿上放置滑动支座，然后将钢梁放于在滑动支座上方。然而当钢梁承受的竖向荷载较大时，为满足承载力要求，支座尺寸必然增加；为满足支座放置的空间需要，牛腿尺寸也相应增加。这样，作用于牛腿上方的竖向力的偏心距就会很大，由此产生的附加弯矩会对柱子的受力产生不利影响。另外，这种构造形式也会造成建筑空间的浪费，影响美观。For some long-span or flexible structures, they tend to produce large deformations under the action of earthquakes or temperatures. When it is necessary to release such structural deformations, sliding bearings are generally installed at appropriate parts of the structures. If this kind of sliding connection is set in the non-top beam-column node area of the steel structure, it is usually to add a corbel at the corresponding position of the column body, place a sliding support on the corbel, and then place the steel beam on the sliding support. However, when the vertical load borne by the steel beam is large, the size of the support must be increased to meet the requirements of the bearing capacity; the size of the corbel is also increased correspondingly to meet the space requirements for the placement of the support. In this way, the eccentricity of the vertical force acting on the top of the corbel will be very large, and the resulting additional bending moment will have an adverse effect on the force of the column. In addition, this structural form will also cause a waste of architectural space and affect the appearance.
因此有必要设计一种钢结构梁柱滑动连接节点，以克服上述问题。Therefore, it is necessary to design a steel structure beam-column sliding joint to overcome the above problems.
