摘要:

制作了3榀格栅管式双钢板混凝土组合剪力墙试验试件，并开展组合剪力墙的低周反复水平荷载试验，绘制出了试件的滞回曲线及骨架曲线。结果表明：格栅管式双钢板混凝土组合剪力墙具有承载能力高、延性好和耗能能力强等优点；新型组合剪力墙可充分发挥格栅式钢墙板和管内混凝土的材料性能，管内混凝土处于三向受压状态，提高了混凝土的抗压强度和延性，外侧钢墙板承担全部拉应力，管内混凝土承担全部压应力，协同工作优势互补；在1/25 rad位移角状态下循环加载80次，新型组合剪力墙塑性铰区域的管内混凝土没有明显的损坏，试验全过程没有任何异响，说明新型组合剪力墙在罕遇地震时也具有良好的工作性能和抗震延性；格栅管式双钢板混凝土组合剪力墙可实现高轴压比、高延性和薄墙厚的抗震剪力墙设计要求。

Abstract:

Three grille type steel plate concrete composite shear wall test specimens were made, and the low-cyclic reversed horizontal load tests on composite shear walls were carried out, then the hysteretic curves and skeleton curves of specimens were draw out. The results show that grille type double steel plate concrete composite shear wall has high bearing capacity, good ductility and strong energy dissipation capacity, etc. The new type composite shear wall can make full use of the material properties of grille type steel plate and in-pipe concrete, and the concrete in the tube is under three pressure condition, which increases the compressive strength and ductility of the concrete. The existence of in-pipe concrete plate and the tie effect of the internal diaphragm plate steel effectively limit the out-of-plane deformation of steel plate, so the grille type steel plate concrete composite shear wall has good ability to resist buckling. When the displacement angle is 1/25 rad, cyclic loading time is 80, the new type of composite shear wall plastic hinge region still has no obvious damage and without any sound in test, which shows that the new composite shear wall also has good working performance during severe earthquake. The grille type double steel plate concrete composite shear wall can realize shear wall design requirements of seismic shear wall with high axial pressure ratio, higher ductility and thinner wall.
