| 摘 要： | 对6片一字形型钢高强混凝土短肢剪力墙试件进行低周反复荷载试验，研究不同型钢配置形式、不同轴压比的型钢高强混凝土短肢剪力墙的承载力、滞回特性及破坏机理。试验结果表明：格构式配钢试件和实腹式配钢试件的破坏过程相近，试件内置实腹式钢板较好地抑制了斜裂缝的发展；轴压比对两种配钢形式试件的承载力和延性影响规律一致，即随着轴压比的提高，试件承载力提高而延性下降；格构式配钢试件承载力比实腹式配钢试件略高，但实腹式配钢试件的延性更好。根据试验结果，提出型钢高强混凝土短肢剪力墙承载力计算式，与试验结果对比表明两者吻合较好。

| Abstract: | Based on low-cycle loading experiment of six specimens of steel reinforced high strength concrete (SRHC) short-pier shear walls with rectangular section, the bearing capacity, hysteretic response and failure pattern of the specimens with different types of steel reinforcement and different compression ratios were studied. The results indicate that lattice steel reinforced specimens and solid steel reinforced specimens exhibit similar damage patterns. Embedded steel plate of the solid steel reinforced specimens effectively inhibits the development of shear cracks. The influences of compression ratios on bearing capacity and ductility for both kinds of steel reinforced specimens are similar, namely, with the increase of axial compression ratios, the loading capacity improves while the ductility becomes worse. Compared with solid steel reinforced specimens, the lattice steel reinforced specimens have higher loading capacity and worse ductility. Based on the test results, strength formulas for SRHC short-pier shear walls were proposed. The formulas are in good agreement with experimental results. |
