多孔砖砌体抗剪强度原位检测的试验研究

Experimental Study on Home Position Test of Shearing Strength of Porous Brick Masonry

多孔砖砌体因具有节约土地能源资源,砌筑效率高,保温隔热和透气性能好等特点,目前已逐步成为砌体结构房屋的主要墙体材料。本文通过多孔砖砌体与标准试件抗剪强度的对比试验研究及试验结果的有限元分析,提出了多孔砖砌体抗剪强度原位双砖双剪的检测方法及其抗剪强度的计算公式。该方法可为多孔砖砌体结构房屋的可靠性评定、房屋建设、事故分析以及抗震加固等提供最基本的技术数据,为多孔砖砌体的应用与推广奠定了基础,并为砌体现场检测技术标准的补充修订提供了依据。

At present, the porous brick masonry has gradually become main wall material of house structure due to its advantages of saving land and energy resources, high efficiency in building, good thermal insulation and ventilating property. By the contrastive test study on shearing strength between porous brick masonry and standard test samples as well as the finite element analysis of the test results, a home position test method of double brick-double shears for shearing strength of porous brick masonry and its shear strength formula are proposed. This method may provide the most basic engineering data for reliability evaluation, house construction, accident analysis as well as anti-seismic reinforcement for house structure of porous brick masonry, lay the foundation of application and the promotion of porous brick masonry, and serve as the basis of supplementary revision of scene test technical standard.
