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
