卧砌土坯墙体加固抗震性能试验研究

Experimental study on seismic performance of lying adobe wall reinforcement

为了提高村镇住宅中既有土坯墙体房屋的抗震性能,提出了采用钢丝网水泥砂浆、木板、木柱木梁及木柱木梁加斜撑等加固措施,该加固措施经济有效、施工方便,符合村镇就地取材的条件。通过对普通卧砌土坯墙体及加固墙片进行抗震性能加固试验,对比分析了各个墙体的破坏形态、承载力、变形、滞回特性、刚度退化及耗能性能,证明了此种加固措施可有效提高土坯墙体的抗震性能。

In order to improve the seismic performance of exiting country adobe wall housing, reinforcement measures, such as the steel wire mesh cement mortar, wood board, timber column and beam, timber column and beam with diagonal brace were proposed. These reinforcement measures were cost-effective and convenient construction under current economic condition of country. Reinforcement experiment on seismic performance of normal lying adobe wall and reinforcement wall was done, and the failure mode, bearing capacity, deformation, hysteresis properties, stiffness degradation and energy dissipation of the wall were analyzed. Seismic performances of wall were improved greatly by the reinforcement measure.
