高强混凝土钢板组合剪力墙压弯性能试验研究

Experimental study of the compression-bending behavior of high-strength concrete steel composite shear walls

通过对9片不同形式的高轴压比高强混凝土组合剪力墙试件进行低周往复拟静力试验,研究钢筋混凝土剪力墙、两端暗柱设置型钢剪力墙和中部内藏钢板剪力墙等形式试件在压弯状态下的破坏机理、滞回特性、承载力特性以及变形能力等。试验结果表明,钢板的加入可以大幅提高剪力墙试件的抗弯承载力,当设计轴压比小于0.5时,高强混凝土钢板组合剪力墙的变形能力可以满足设计要求,当设计轴压比超过0.5时,高强混凝土钢板组合剪力墙试件在受弯状态下的变形能力较弱。根据试验结果,提出了高强混凝土钢板组合剪力墙抗弯承载力计算的建议公式。

The compression-bending behavior of 9 high-strength concrete shear wall specimens with high axial compression ratios were tested under low-frequency cyclic lateral loading. The specimens included reinforced concrete （RC） walls, steel reinforced concrete （SRC） walls, and steel plate-concrete composite （SPRC） walls. Based on the experimental results, the failure pattern, hysteretic properties and deformability of RC walls, SRC walls, and SPRC walls were studied. The results show that embedded steel plate effectively improved the bearing capacity, and the ductility of SPRC walls can meet the design requirements when the axial compression ratio is less than 0.5. Based on the test results, capacity formula for SPRC walls was proposed.
