型钢–钢板混凝土组合墙抗震性能试验研究
|
摘要
提出一种型钢–钢板混凝土组合墙,为了研究其抗震性能,设计制作该形式的型钢–钢板混凝土组合墙进行拟静力试验。通过改变试件的轴压比、剪跨比,研究其在低周往复载荷作用下的受力机理、滞回性能、刚度退化及耗能能力等。试验结果表明:试件的破坏形态为压弯破坏,组合墙两端方钢管正面及侧面发生撕裂,两侧底部钢板屈曲严重,混凝土压溃;随着轴压比减小,试件具有更好的塑性变形能力和耗能能力,剪跨比对组合墙的抗震性能影响较小。
This paper proposes an innovative composite wall, named the section steel-steel plate concrete composite shear wall. The seismic behavior of the composite walls is examined and the results of the quasistatic cyclic tests on the walls designed and machined are presented. The failure mechanism, the hysteretic behavior, the stiffness degradation and the energy dissipating capacity are investigated under various axial load ratios and shear span ratios. The test results indicate that the specimens fail in a flexural mode, the steel tubes are torn on the front and the side, characterized by the local buckling of the boundary steel plates and the compressive crushing of the concrete at the wall base. For the composite walls, the plastic deformation ability and the energy dissipation capacity are improved with the increase of the axial load ratios, while the shear span ratio has less effect.
