摘要
文章通过试验研究了大纵向钢筋间距时,提高横向钢筋配筋率对短肢剪力墙性能的影响。结果表明,纵向钢筋的间距过大时,裂缝在暗柱区域和中间区域交接处会出现转折;当横向钢筋配筋率增加时,腹部裂缝分布趋向合理,但试件的极限承载能力提高不多,试件水平位移和位移延性有少量增加;试验的滞回曲线有明显的"捏缩"现象,说明此配筋形式的短肢剪力墙耗能性能不理想。
The quasi-static tests are made to investigate the effect of transverse reinforcement ratios on the capability of short-limb shear-walls with large span longitudinal rods, and the results are analyzed. When the specimens with longitudinal rods had three step-up transverse reinforcement ratios, the capability of short-limb shear-walls had not shown the relevant change. The hysteresis loops indicate that this type of reinforcement is not good for energy dissipation.
