| 摘 要： | 为研究内填砌块点接触式密肋复合墙体的抗震性能,进行1/2缩尺比例的复合墙体低周反复加载试验,分析墙体的主要破坏形态和破坏过程,研究点接触型密肋复合墙体的受力特点,分析墙体的滞回特征、承载力、延性、刚度和耗能能力等抗震性能,并将试验结果与标准墙体试验结果进行对比.研究结果表明:点接触式墙体与标准墙体的破坏形态区别较大,其承载力、延性、耗能等性能略差于标准墙体,但由于这一形式墙体各道防线之间的地震作用传递途径和分配关系相对明确,不同阶段的墙体计算模型比较简单,进而可以通过对各阶段的精确分析计算实现密肋结构的控制设计.此外,墙体各道防线之间的分离更易于结构构件的震后修复、更换.

| Abstract: | In order to research the seismic performance of point contact multi-ribbed composite wall,a low-cycle reverse loading test of 1/2 scale point contact multi-ribbed composite wall was carried out.Based on the experimental study,the failure processes and main failure modes were studied and meanwhile the behavior of the wall was discussed,moreover the hysteretic behavior,load-carrying capacity,ductility,stiffness,energy dissipation were analyzed.The experimental data and the standard multi-ribbed composite wall... |
