Abstract
Non-autoclaved and non-sintered fly-ash perforated brick is a kind of new material for non-load-bearing walls. In order to promote the application of this new material in village and town buildings of seismic area, compression and shear strength of non-autoclaved and non-sintered fly-ash perforated brick masonry was tested and crack and failure progress was analyzed. The test results show that the failure processes and characteristics of the non-autoclaved and non-sintered fly-ash perforated brick masonry in compression and in shear are similar to that of the common brick masonry, however the non-autoclaved and non-sintered fly-ash perforated brick masonry tend to fail in brittle manner. The compression and shear strength are all less than that of the common brick masonry. A mathematic model of 6 degrees polynomial was used to express the compressive constitutive relationship and the whole process of non-autoclaved and non-sintered fly-ash perforated brick masonry in compression was described. The curve was close to the measured data.
