为研究偏心距e对蒸压粉煤灰实心砖砌体承载力性能的影响,以e为主要参数,对24个蒸压粉煤灰实心砖砌体试件及4个普通粘土砖砌体试件进行偏心受压试验。试验结果表明,砌体的偏心受压承载力随e值的增加线性降低,偏心影响系数φ的试验值略低于规范计算值。建议蒸压粉煤灰实心砖单向偏心受压构件的偏心距限值取0.6y,并通过试验回归对规范中φ的计算式进行了调整,其计算结果与试验结果相近。 In order to study the influence of eccentricity e on the bearing capacity of autoclaved fly ash solid brick masonry, taking e as the main parameter, 24 autoclaved fly ash solid brick masonry specimens and 4 ordinary clay brick masonry specimens Eccentric compression test pieces. The test results show that the eccentric compressive bearing capacity of masonry linearly decreases with the increase of e value, and the test value of eccentric influence coefficient φ is slightly lower than the standard calculation value. It is suggested that the eccentricity limit of one-way eccentric compression member of autoclaved fly ash solid brick should be 0.6y, and the formula of φ in the specification should be adjusted through the test regression. The calculation results are similar to the test results.
