The pseudo-static test about wall bricks was conducted, which inuolved 7 autoclaved fly ash wall bricks, 2 autoclaved fly ash perforated wall bricks and 2 fired common wall brick walls. Furthermore, a comparative analysis of failure patterns was carried out. The constructional column and vertical compress stress which had an effect on seismic behavior of walls was also analysed. The analysis result of the test showed that the shear strength and other seismic behaviors of autoclaved fly ash wall bricks and fired common wall bricks were similar. And the seismic design for autoclaved fly ash bric...
