【摘要】 据统计,2002年以前的房屋建筑结构中砌体结构约占结构总数的90%,也是校舍结构的主要形式,其中纵墙承重结构体系又占多层砌体结构的一半以上。在大部分多层砌体教学楼中,一般房屋的横墙较少,传统的砌体结构加固方法对于外纵墙小墙肢的抗震能力提高并不明显。通过小墙肢组合柱与普通砌体及传统方式加固砌体的对比试验,分析了小墙肢组合柱加固方式的受力特性并推导出其承载力计算公式,为砌体结构加固方法的研究提供一定的理论指导。更多还原

【Abstract】 According to statistics,the masonry structures accounted for about 90% of the housing structures before 2002,which is the main form of the campus structures,of which the load-bearing structures of the vertical wall systems accounted for more than half of the multi-story masonry structures.In most of the multi-story masonry classroom buildings,there is less transverse wall in the house.And the effect of traditional masonry structure reinforcement method for the outer vertical wall to improve the seismic capacity of the pier is not obvious.Through contrast test of composite small pier column masonry with ordinary masonry and traditional reinforced way,this article analysied the pier reinforcement force characteristics and derived its bearing capacity formula.更多还原
