FRP mixed reinforcement coupled shear wall structure with replaceable component
The invention discloses a function-recoverable FRP mixed reinforcement coupled shear wall structure with replaceable wall foot components and replaceable coupling beam components. The function-recoverable FRP mixed reinforcement coupled shear wall structure comprises wall columns, replaceable coupling beams, replaceable wall feet, a floor slab and a lower constraint beam. The replaceable coupling beam of the shear wall comprises non-replaceable concrete coupling beam sections at the two ends and a replaceable energy dissipation I-shaped steel beam section in the middle. A gap is formed between the coupling beam upper floor slab and the coupling beam and is subjected to connectionless treatment; a novel friction energy dissipater is arranged on the replaceable wall foot, and the novel friction energy dissipater resists tension through friction force and resists compression through steel pipe concrete and friction force; a built-in steel truss is additionally arranged at the bottom of the shear wall column; and the longitudinal stress bars of the wall body adopt an FRP (Fiber Reinforce Plastic) mixed reinforcement form with strength gradient. Damage and energy consumption of the novel shear wall structure system are mainly concentrated on the replaceable connecting beams and the replaceable wall feet, damage to the floor slabs is reduced through unbonded treatment between the floor slabs and the connecting beams, the shear resistance of the replaceable areas of the wall bodies is improved through the built-in steel trusses, and the FRP ribs are always in the elastic stage, so that the self-resetting performance of the wall bodies is guaranteed. The FRP mixed reinforcement coupled shear wall with the replaceable wall foot component and the replaceable coupling beam component has the advantages of being excellent in bearing performance, energy consumption performance and self-resetting performance.
一种带可更换墙脚构件和可更换连梁构件的可恢复功能FRP混合配筋联肢剪力墙结构，包括墙肢、可更换连梁、可更换墙脚、楼板、下约束梁。该剪力墙可更换连梁包括两端非更换混凝土连梁段、中间可更换消能工字钢梁段；连梁上部楼板与连梁间设有缝隙，做无连接处理；可更换墙脚设置新型摩擦耗能器，新型摩擦耗能器通过摩擦力抗拉，通过钢管混凝土及摩擦力抗压；剪力墙墙肢底部增设内置钢桁架；墙体纵向受力筋采用具有强度梯度的FRP混合配筋形式。这种新型剪力墙结构体系损伤与耗能主要集中在可更换连梁及可更换墙脚，楼板与连梁间的无粘结处理减少楼板的损伤，内置钢桁架改善了墙体可更换区域的抗剪能力，FRP筋始终处于弹性阶段保证了墙体的自复位性能。这种带可更换墙脚构件和可更换连梁构件的FRP混合配筋联肢剪力墙具有承载、耗能、自复位性能均优的特点。
