摘要：

为研究偏心率e／y对蒸压粉煤灰多孔砖砌体承载力性能的影响。以e／y为主要参数,对24个蒸压粉煤灰多孔砖砌体试件及4个普通黏土砖砌体试件进行偏心受压试验,分析其受压破坏形态。通过试验研究表明砌体的偏心受压承载力随e／y值的增加而呈线性降低。偏心影响系数φ试验值略低于规范中规定值。对规范中φ公式进行调整,给出蒸压粉煤灰多孔砖无筋砌体矩形截面单向偏心受压构件承载力的建议计算公式,并建议蒸压粉煤灰多孔砖单向偏心受压构件的偏心距限值为0.6y。

Abstract:

The influence of the eccentricity on the capacity of autoclaved fly ash perforated brick masonry was studied. The eccentric compression tests were done on 24 autoclaved fly ash perforated brick masonry samples and 4 fired common clay brick masonry samples, of which the damage pattern was analyzed. The results indicated that the eccentric compression capacity accorded to a certain proportional decrease as the e／y increased, and the eccentric effect factor was slightly lower than Chinese code values. In conclusion, the adjust formula of eccentric effect factor in code. The proposed formula of the eccentric compression bearing the capacity of autoclaved fly ash perforated brick masonry was given, which suggested that the limit value of eccentricity of autoclaved fly ash perforated brick unidirectional eccentric compression members take e=0.6y.

Key words: masonry, autoclaved fly ash perforated brick, capacity, eccentric effect factor
