Vibration reduction sub-frame containing partial encased concrete combination column-combination assembly type energy dissipation beam
The invention discloses a vibration reduction sub-frame containing a partially wrapped concrete combination column-combination energy dissipation beam, and belongs to the technical field of seismic resistance and shock absorption of structural engineering. Compared with steel columns such as H steel and square steel pipes, the partially-wrapped concrete combination column formed by filling concrete is higher in rigidity and bearing capacity, high-performance reinforced fiber cloth is pasted to the upper column end and the lower column end of the partially-wrapped concrete combination column for local reinforcement, the column joint bearing capacity is higher, and the aseismic design requirements of'strong columns, weak beams, strong joints and weak components' are met; the combined assembly type energy dissipation beam is a combined assembly type beam system composed of an end beam, an I-shaped energy dissipation beam and a middle beam, an upper flange and a lower flange of the energy dissipation beam are provided with flange connecting plates and are in an I shape, the flanges are of a dog bone type structure, a web is of a circular or rhombic hole forming form, and the energy dissipation beam can fully absorb earthquake energy under the earthquake action and can effectively absorb earthquake energy. And it is guaranteed that when an earthquake occurs, only the energy dissipation beam section generates yield failure, other beam sections are kept intact, and only the damaged energy dissipation beam needs to be replaced during repairing.
本发明公开了一种含部分外包混凝土组合柱‑组合耗能梁的减振子框架，属于结构工程抗震与减震技术领域；相对H钢、方钢管等钢柱，由混凝土填充形成的部分外包混凝土组合柱刚度和承载力更大，且部分外包混凝土组合柱上下柱端粘贴高性能增强纤维布进行局部加强，柱节点承载力更强，符合“强柱弱梁、强节点弱构件”的抗震设计要求；组合装配式耗能梁由端梁、“工字型”耗能梁和中梁组成组合装配式梁体系，耗能梁上下翼缘自带翼缘连接板，呈“工字型”，翼缘采用狗骨式构造、腹板采用圆形或菱形开洞的形式，地震作用下耗能梁将充分吸收地震能量，保证在地震发生时只有耗能梁段发生屈服破坏，其他梁段保持完好，修复时只需要更换破坏的耗能梁即可。
