Novel dog-bone type connection joint unit of assembly type buckling-restrained brace steel frame structure
The invention relates to the technical field of building structures, in particular to a novel dog-bone type connecting joint unit of an assembly type buckling-restrained brace steel frame structure. The unit aims to solve the technical problems of fracture lag and small joint plastic zone in the prior art. A joint plate assembly is located in a beam-column joint area formed between a column and a beam and used for connecting the column and the beam; one end of the buckling-restrained brace steel frame structure is connected to the joint plate assembly, and the other end of the buckling-restrained brace steel frame structure is connected to a preset fixing position of the other beam; and the dog bone type joint structure is constructed at the end part of the beam. According to the technical scheme, an elastic-plastic displacement angle limit value exceeds 2% of the standard, a beam flange of a cross section is weakened, plasticity is fully developed, a plastic hinge is formed, the buckling-restrained brace steel frame structure dissipates a large amount of energy after being subjected to repeated tension-compression plastic deformation, and finally an unrestrained connecting section is bent.
本发明涉及建筑结构技术领域，特别涉及一种新型装配式防屈曲支撑钢框架结构狗骨式连接节点单元，以解决现有技术中存在断裂滞后、节点塑性区小的缺陷的技术问题。节点板组件位于柱与梁之间形成的梁柱节点区域，并用以连接所述柱与所述梁；防屈曲支撑钢框架结构，其一端连接在所述节点板组件上，其另一端连载在另一梁的一预设固定位置上；狗骨式节点节点结构构造在所述梁的端部；本技术方案能够超过规范2％的弹塑性位移角限值，削弱截面的梁翼缘充分发展塑性，形成塑性铰，防屈曲支撑钢框架结构在经历了反复的拉压塑性变形后，耗散了大量能量，最终无约束连接段发生屈曲。
