［摘要］結(jié)合砌體結(jié)構(gòu)文物保護單位保護修繕項目，開展了以純白灰、白灰砂漿、摻灰泥等傳統(tǒng)灰漿為粘結(jié)材料的手工青磚砌體抗剪強度試驗。研究了該類砌體受剪的破壞特征和形式，分析了《砌體結(jié)構(gòu)設(shè)計規(guī)范》（GB 50003—2011）中燒結(jié)普通磚砌體抗剪強度平均值計算式在該類砌體中的適用性。結(jié)果表明，以傳統(tǒng)灰漿為粘結(jié)材料的手工青磚砌體受剪破壞具有脆性破壞特征，破壞形式有單剪破壞和雙剪破壞2種形式，抗剪強度平均值試驗結(jié)果明顯低于燒結(jié)普通磚砌體規(guī)范計算式的計算結(jié)果。根據(jù)試驗結(jié)果，采用最小二乘法對規(guī)范抗剪強度平均值計算式進(jìn)行了修正，建立了適用于以所研究的傳統(tǒng)灰漿為粘結(jié)材料的手工青磚砌體抗剪強度平均值計算式，確定了該類砌體抗剪強度設(shè)計值。

Abstract:Combined with the renovation and protection of masonry structure projects of cultural relics protection unit, the shear strength tests of the manual gray brick masonry with traditional mortars made of lime, lime-sand, mud-lime as bonding materials were carried out. The shear failure characteristics and forms of this kind of masonry were studied. The applicability of the formula for calculating the average shear strength of sintered ordinary brick masonry in Code for design of masonry structure (GB 50003—2011) in this kind of masonry was analyzed. The results show that the shear failure of manual brick masonry with traditional mortars as bonding materials has the characteristics of brittle failure. Its failure forms are single shear failure and double shear failure, and the test result of average shear strength is significantly lower than calculation result of sintered ordinary brick calculated by masonry code calculation formula. According to the test results, the formula for calculating the average shear strength in the code was modified by the least square method, and a formula for calculating the average shear strength of manual gray brick masonry with traditional mortars as bonding materials was established. The shear strength design values of this kind of masonry were determined
