仿照古方法,加入糯米浆拌制石灰砂浆和石灰黏土砂浆,用这两种砌筑砂浆和水泥砂浆分别与历史建筑拆除下的人工砖砌成短柱,进行轴心抗压试验,计算出砌体现有承载力,并分析其应力-应变曲线的特点。考虑3组砌体的材料匹配性,依照《砌体结构设计规范》(GB50003—2001)中给出的砌体抗压强度平均值计算公式,提出了应用于历史保护建筑砖结构现有承载力的计算公式。
According to the ancient method, adding glutinous rice slurry mixed with lime mortar and lime clay mortar, masonry mortar and cement mortar with the demolition of the historic buildings were short columns of artificial brick, axial compression test, calculate the puzzle Reflect the bearing capacity, and analyze the characteristics of its stress-strain curve. Considering the material matching of three groups of masonry, according to the formula of average value of compressive strength of masonry given in “Code for Design of Masonry Structure” (GB50003-2001), the existing bearing capacity The formula.
