Introduce Testing Method of Detect Shear Strength of Masonry by Drilled Core Method

钻芯法检测砌体抗剪强度直接从砌体中钻取芯样,对砌体芯样进行加工处理后,进行芯样沿通缝截面抗剪强度试验,得到砌体芯样抗剪强度,进而推定砌体抗剪强度;钻芯法检测砌体抗剪强度关键技术包括钻取芯样位置、芯样尺寸、芯样处理、芯样沿通缝截面抗剪强度试验、数据处理。本技术既适用于传统砌体结构,又适用于新型墙材砌体结构,特别适用于砌体结构抗震鉴定及加固验算。钻芯法检测砌体抗剪强度技术为新型墙体材料质量检测评定及工程质量事故分析处理提供了科学依据。

Shear strength of masonry is directly related to the seismic performance of masonry structure ~ the experiment proved that shear strength of core samples from masonry have closely related to standard shear strength of masonry; Testing masonry shear strength with drilled core method, directly drilling core samples from masonry, after core samples processed, test the shear strength of core samples （along straight joint）, then according to the shear strength of masonry core sample we can presumed out standard shear strength of masonry; key technology of testing masonry shear strength with drilled core method include： Location of Drilling core sample, Size of core sample, method of processing core sample, method of testing the shear strength of core samples and data processing. This Technology can be suitable both to traditional masonry structure and to new wall materials masonry structure, especially to seismic appraiser and reinforcement calculation of masonry structure. This technology can support scientific basis to quality examination and assessment of new wall materials and analysis of engineering quality accident.
