Abstract:  Through the comparative analysis of the experimental method and result about the seismic shear strength of fired common brick masonry and concrete hollow block masonry, it was found that the formula of the seismic shear strength of hollow concrete block masonry in Code for seismic design of building (GB50011 -2001)  is not safe enough. Statistical analysis about 58 walls experimental result has been carried out. Finally, a reasonable seismic shear strength formula for concrete hollow block masonry is proposed.
