摘要:
通过6片高强钢筋高强混凝土短肢剪力墙进行低周往复荷载试验,对不同轴压比、高厚比和配箍率的高强钢筋高强混凝土短肢剪力墙的破坏形态、滞回性能等方面进行分析,研究其破坏机理和抗震性能.依据试件各阶段破坏规律,分析对比既有地震损伤模型,提出了适用于高强钢筋高强混凝土短肢剪力墙的双参数地震损伤模型.分析实验结果证明:剪跨比和轴压比是高强材料短肢剪力墙试件破坏形态的主要影响因素; 相较普通短肢剪力墙其承载力、耗能能力等抗震性能更为优秀,承载力提升可达52%; 对高轴压比及高厚比的试件采用箍筋加密的构造措施可使延性提升20%以上; 提出的模型符合试件破坏发展历程和损伤机理,给出了各阶段损伤指数所对应的试验损伤程度,为其震后损伤评估提供参考依据.
Abstract:
Through the low-cycle reciprocating load test of 6 pieces of high-strength reinforced concrete short-leg shear walls, the failure mode and hysteretic performance of high-strength reinforced concrete short-leg shear walls with different axial compression ratios, height-to-thickness ratios and hoop ratios were analyzed to study its damage mechanism and seismic performance. According to the failure laws of the specimens at various stages, the existing seismic damage models were analyzed and compared, and a two-parameter seismic damage model suitable for high-strength steel and high-strength concrete short-limb shear walls was proposed. The experiment results showed that the shear span ratio and axial compression ratio were the main influencing factors of the failure mode of high-strength short-leg shear wall specimens; compared with ordinary short-leg shear walls, its bearing capacity, energy dissipation capacity and other seismic performance were better, and the bearing capacity could be increased up to 52%; the ductility of specimens with high axial compression ratio and high thickness ratio could be improved by more than 20% by using stirrup densification. The model proposed in this research is consistent with the failure development process and damage mechanism of specimens, and the test damage degree corresponding to the damage index at each stage is given, which can provide a reference for the post-earthquake damage assessment.
