蒸压粉煤灰砖是目前我国重点推广的墙体建筑材料之一,在内蒙古地区由于对蒸压粉煤灰砖砌体的研究较少,严重限制其在实践工程中的推广使用。本文的主要目是研究蒸压粉煤灰墙体的荷载-位移曲线、延性系数、破坏形态和不同正应力对墙片实验结果的影响及构造柱的加设对墙顶抗剪承载力的影响作用。用实验数据与现有的砌体抗剪强度计算理论对比得出本文的建议结论。
Autoclaved fly ash bricks are one of the most widely used wall building materials in our country. In Inner Mongolia, due to the limited research on autoclaved fly ash brick masonry, its application in the practical engineering is severely restricted. The main purpose of this paper is to study the effects of load-displacement curve, ductility coefficient, failure mode and different normal stresses on the experimental results of the wall of autoclaved fly ash walls and the influence of the addition of structural columns on the shear capacity of the wall effect. The proposed conclusions of this paper are obtained by comparing the experimental data with the existing theoretical calculation of shear strength of masonry.
