Abstract:In order to establish a calculation formula for the shear capacity of the reinforced wall strengthened by steel bar-mortar layer crossed strip, and to analyze the common working mechanism between steel bar-mortar layer crossed strip and the mother wall,  the  pseudo-static test of 12   single walls with aspect ratio not greater than 1 was put up. The test results show that if  steel bar-mortar layer crossed strip with 40～60mm thick and 250～300mm width is added to the brick wall on one side or both sides,  the seismic performance of the masonry wall is greatly improved. The ultimate bearing capacity of the reinforced wall is more than 40% higher than that of the unreinforced wall, and the ductility is obviously improved. The calculated values of the calculation formula of the shear capacity of the composite wall after reinforcement by mechanism analysis and numerical fitting are in good agreement with the experimental values.

Keywords:steel bar-mortar layer crossed strip method; masonry wall; pseudo-static test
