目前配筋砌体结构存在的配筋层砂浆灰缝较厚,不利于墙体节能保温,分析了无筋、水平配钢筋和水平配纤维布的A类蒸压加气混凝土砌块墙体在水平荷载作用下的伪静力试验,结果表明:水平配钢筋砌块墙体抗震性能最好,水平配纤维布次之,无筋普通砂浆砌筑墙体较差;水平配纤维布可以提高结构的延性,但提高的程度有限,纤维布本身相对于钢筋较弱.提出采用纤维格栅土工材料替代配筋砌体中的水平钢筋.鉴于纤维格栅替代配筋砌体中的水平钢筋是一种创新尝试,对纤维格栅配筋砌体的特性进行了探讨,提出了具体需要进行的必要验证及理论研究.有利于砌体结构抗震、推广应用薄灰缝砌体及促进建筑节能的发展.
The present reinforced masonry structure has thicker mortar joints of mortar layer, which is not conducive to energy saving and heat preservation of the wall. The A type autoclaved aerated concrete block wall without reinforcement, horizontal reinforcement and horizontal fiber cloth The results show that the wall with horizontal rebar block has the best seismic performance, the horizontal with fiber cloth, and the normal mortar with no mortar masonry wall is inferior. The horizontal with fiber cloth can improve the structure However, the degree of improvement is limited, and the fiber cloth itself is weaker than that of the steel bar. It is proposed to replace the horizontal bar in the reinforced masonry with fiberglass geogrids. This paper discusses the characteristics of fiberglass reinforced masonry and puts forward the necessary verification and theoretical research on the specific needs, which is good for the seismic resistance of masonry structures, promoting the application of thin gray cement masonry and promoting the development of building energy conservation .
