混凝土多孔砖和组合配筋砖小截面墙体抗震性能的试验研究

Test studies on seismic behavior of perforated concrete bricks and small section masonry reiforcing walls

针对农村窗间墙过窄的现状,提出一种组合配筋砌体以抵抗地震剪力,并提出混凝土多孔砖组合配筋砌体的参考公式.通过对混凝土多孔砖和组合配筋砖小截面墙体进行反复荷载下的抗震性能试验研究,讨论两种不同类型砌体的破坏特征、滞回特性、骨架曲线和抗剪强度等问题.组合配筋砌体与无筋砌体相比,抗震性能明显提高,延性增强。结果表明组合配筋砌体是一种能够明显改善小截面墙体抗震性能的实用方法,可在农村地区推广。

It is in view of that countryside window between walls excessively is narrow,a reinforced masonry wall and a reference formula are proposed.Based on the earthquake resistant performance tests of concrete perforated bricks and small section masonry reinforcing walls under repeated loads,their failure forms,hysteresis loops,skeleton curves and shear strength etc are analysed.The masonry reinforcing wall is compared with the ordinary wall,the masonry reinforcing walls have better earthquake resistant performance and ductility.The masonry reinforcing walls are adopted to be a practical method that improves the earthquake resistant performance of the small section walls.
