摘　　要：通过对4片西北地区传统土坯墙体在低周往复荷载作用下的抗震性能试验研究,对比分析了竹胶板及木柱木梁加固墙片的破坏形态、水平承载力、变形性能、骨架曲线、刚度退化曲线、滞回曲线与耗能性能。试验研究表明:加固墙片可有效提高墙体的抗震性能。在此基础上提出用竹胶板加固既有且在用的村镇土坯墙体房屋,该加固方式经济有效,又能在一定程度上保存建筑原始风貌,满足实际工程的设计要求。Based on the experimental study on the seismic performance of four traditional adobe walls in the northwest area under cyclic loading,the failure mode,horizontal bearing capacity,deformation behavior,skeleton curve,stiffness degradation curve,hysteresis curve,and energy dissipation capacity of the adobe walls reinforced by the bamboo rubber sheet,and wooden pillars and beams were compared and analyzed.The results show that the reinforcement measures can effectively improve the seismic performance of the wall.On this basis,it is proposed to strengthen the adobe walls existed and used in the villages and towns with bamboo rubber sheet,which would be economical and effective,and can save the traditional style of the buildings to some extent to meet the requirements of the actual engineering design.
