Capacity And Deformability Of Vertically Sheared Clay Brick Masonry With Horizontal Reinforcement

Summary

Test results for reinforced and unreinforced masonry walls subject to shearing perpendicular to the bed joints are compared.  The main aim was to determine the influence of smooth reinforcement, placed in horizontal bed joints, on tangential stress levels at the moment of cracking, maximum shearing stress at the moment of masonry failure, and Kirchhof's modulus for vertically sheared masonry walls.  The results showed that applied reinforcement, with the tested reinforcement ratio, does not affect or has an insignificant effect on the mechanical parameters  The results show the need for further study of masonry containing higher reinforcement ratios (e.g. rho = 0.10% or 0.15%).  Investigations should also include unreinforced masonry and masonry with horizontal reinforcement made from masonry units having a greater freedom of in-plane displacement.  9 refs.
