［摘要］對35個(gè)沿水平灰縫開槽并后嵌不同強(qiáng)度砂漿的普通燒結(jié)磚砌體進(jìn)行了沿通縫抗剪試驗(yàn)，分析了嵌縫砂漿磚砌體沿通縫抗剪破壞特征和抗剪強(qiáng)度特征，建立了嵌縫砂漿磚砌體沿通縫抗剪強(qiáng)度計(jì)算公式，公式的計(jì)算值與試驗(yàn)結(jié)果吻合較好。試驗(yàn)研究表明隨著嵌縫砂漿強(qiáng)度的提高，砌體抗剪強(qiáng)度也隨之提高，因此嵌縫砂漿能有效地提高磚砌體的抗剪強(qiáng)度。

Abstract:Shear tests were performed on 35 brick masonry specimens, which were slotted along horizontal joint and embedded in mortars of different strength. The shear failure characteristics and shear strength characteristics of masonry specimen were analyzed. The shear strength along horizontal bed joint formula of the masonry was established. The calculated values, which were generated by formula developed in this method, were consistent with the experimental results. Experimental studies shows that the shear strength of masonry was improved with the increase of the strength of mortar, so caulking mortar can improve the shear strength of masonry effectively.
Keywords:masonry structure； embedded mortar along horizontal bed joint； shear strength； mortar strength
