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
