Fabricated vibration reduction wall of PEC composite column-composite energy dissipation beam and mounting method of fabricated vibration reduction wall of PEC composite column-composite energy dissipation beam
The invention discloses a PEC composite column-composite energy dissipation beam assembly type vibration reduction wall and a mounting method, and belongs to the technical field of structural engineering seismic resistance and vibration reduction. The novel fabricated wall is applied to a main body frame to enhance the anti-seismic property of the structure, and the lateral stiffness and the energy dissipation capacity of the structure can be improved. Wherein the combined energy dissipation beam is formed by connecting, combining and assembling an end beam, an energy dissipation beam and a middle beam through bolts, weakening parts of an upper flange and a lower flange of the energy dissipation beam are replaced by metal materials with high energy dissipation capacity, the energy dissipation beam section can fully absorb earthquake energy under the action of an earthquake, and it is guaranteed that only the energy dissipation beam section is subjected to yield failure when the earthquake occurs; other beam sections are kept intact, only damaged energy dissipation metal plates or energy dissipation beams need to be repaired or replaced during repairing, and steel is saved to the maximum extent; the UHPC high-strength fiber concrete, the rubber concrete and the UHPC high-strength fiber concrete are sequentially filled in the PEC combination column from the upper column section to the lower column section, and the overall anti-seismic and vibration-reducing performance of the vibration-reducing wall column is better.
本发明公开了一种PEC组合柱‑组合耗能梁的装配式减振墙体及安装方法，属于结构工程抗震与减震技术领域；应用于主体框架中以增强结构抗震性能的新型装配式墙体，可以提高结构抗侧刚度和耗能能力；其中，组合耗能梁包括端梁、耗能梁和中梁通过螺栓连接组合装配而成，耗能梁上下翼缘的削弱部分置换为耗能能力强的金属材料，地震作用下耗能梁段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，修复时只需要修复或更换破坏的耗能金属板或耗能梁即可，最大程度节约钢材；PEC组合柱内部由上部柱段至下部柱段依次填充UHPC高强纤维混凝土、橡胶混凝土、UHPC高强纤维混凝土，减振墙体柱的整体抗震减震性能更优。
