The normal formula is recommended to calculate the compressive strength of the masonry. The shear strength calculation formula of recycled concrete hollow block masonry is proposed according to the formula of masonry design code. The calculating results are in good agreement with the test results.Keywords: recycled concrete hollow block masonry; compressive strength; shear strength
