砖石结构设计规范(GBJ3—73)规定,砖石砌体抗压强度试验,试件截面尺寸采用37×49cm,砌体高度与较小边长的比值可采用2.5～3.0,当试件截面采用其它尺寸时,抗压强度应按试验结果乘以截面尺寸影响系数ψ值后采用。 对截面尺寸为37×49cm砖砌体试件进行抗压试验。需要大吨位试验设备。同时,大截面试件较笨重,给运输、试验带来困难,造成材料、人力的浪费。所以,即使试验条件较好
Masonry structure design specification (GBJ3-73) stipulates that for masonry masonry compressive strength test, the cross section size of the test piece shall be 37×49cm, and the ratio of masonry height to the minor side length may be 2.5-3.0, when the test piece cross-section When other dimensions are used, the compressive strength shall be used after multiplying the test result by the cross-sectional size influence factor ψ. The compressive test was carried out on a brickwork specimen with a section size of 37×49 cm. Large tonnage test equipment is needed. At the same time, large-section test specimens are bulky, causing difficulties in transportation and testing, and causing waste of materials and manpower. So even if the test conditions are better
