［摘要］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。

Abstract:The sticky rice was added in the lime mortar and clay lime mortar with the archaic method. The short columns were built by laying artificial bricks with cement mortar, lime mortar and clay lime mortar respectively. Axial compressive strength test was carried out. The bearing capacity of the brick masonry was calculated and the analysis of the stress-strain curves was given. Considering the adaptability of the three groups of brick masonry,  according to the formula for the average compressive strength of brick masonry, the formula for the present capacity of historical preserved buildings was given.

Keywords:historical preserved building; brick masonry structure; artificial brick; sticky rice lime mortar; bearing capacity test
