摘要
对砌体无机植筋的抗拔和抗剪性能进行了试验研究,探讨了不同植筋深度和砂浆强度等级对砌体植筋的抗拔承载力的影响及破坏机理,以及植筋对砌体与砂浆粘结面抗剪性能的影响。试验得到了砌体无机植筋的最小植筋深度和施工要求;结果表明无机植筋能显著提高砌体与砂浆粘结面强度。
In this article a pull-out test and a direct shear test of inorganic embedded-bar in brick masonry are taken in order to study the effects of embedded depth and mortar strength, and the shear strength of inorganic embedded-bar is investigated experimentally using a direct shear test including nine specimens. The smallest embedded depth and the construction method on brick masonry are proposed by the experiment. The results also show that the inorganic embedded bar can remarkably raise the interface strength.
