Based on the physical model test and numerical simulation analysis, the bond-slip behavior between shale porous brick and mortar was investigated.The 48 specimens made of two types of porosity shale porous brick with different mortar strength grades were conducted by double-sided shear tests and the bond failure mode,the bonding strength and the bond strength-slip curve were obtained.The calculating formulas of bond strength of porous brick masonry and the bond-slip constitutive models were established.The results of finite element simulation of separated micro mechanical masonry model accordi...
