配筋砌块砌体墙体抗剪性能影响因素的试验研究

主要对采用构造柱-芯柱配筋混凝土小型空心砌块砌体进行抗剪能力的试验研究.由于水平筋及高宽比对配筋砌体剪力墙中抗剪的提升作用是不可忽略的,通过试验研究了不同参数的两组墙体,并分析了水平钢筋与高宽比对配筋砌块砌体抗剪承载能力的影响.试验结果表明,水平钢筋有利于砌体结构抗剪性能的提高;在一定范围内,高宽比越低,抗剪性能越好.

The Experimental Research for Reinforced Concrete Masonry Structure Ability to Resist Lateral Force

This thesis focuses on the experimental analysis of the reinforced masonry shear wall with restricting constructional columns at the boundary and some core columns in it.The increase of the shearing strength by means of the proportion of horizontal reinforced steel bars to the depth-width in the reinforced masonry shear walls is obvious.In light with the experiments with two groups of walls which have different parameters,this article analyzes the influence of the portion of horizontal reinforcing steel to the depth-width on the masonry structure ability to resist lateral force.The results indicate： the horizontal steel is conducive to the wall＇s ability of resist lateral force,and the smaller the depth-width ratio is,the better the ability to resist lateral force is,to some extent.
