常用砌筑砂浆砌块砌体基本力学性能的研究

Basic mechanical properties of common mortar block masonry

根据现行砌体基本力学性能试验方法标准和砌体结构设计规范,对混凝土小型砌块常用砌筑砂浆砌块砌体的基本力学性能进行了试验研究。结果表明,三种砌筑砂浆砌块砌体抗压强度设计值均能满足现行规范规定砌体抗压强度设计值要求,并超出设计值99%～116%;三种砌筑砂浆中,只有混凝土小型砌块专用砌筑砂浆砌块砌体沿通缝截面的抗剪强度设计值能满足规范规定的要求,超出了设计值78%,并对其机理进行了探讨。

Based on the existing standard of test method for masonry basic mechanical properties and code tbr design of masonry structures, the basic masonry mechanical properties of three masonry mortars were studied.The results show that block masonry compressive strength design value of three masonry mortar masom＇y can meet requirements which are ruled and exceed the design values 99%-116%;1n the three masonry mortar, only block masonry shear strength design value of the section along continuous seam of small hollow concrete block by special masonry mortar can meet the design requirements of shear strength which are ruled and exceed the design value 78%, and its mechanism was discussed.
