An experimental study of the behaviour of hollow clay brick masonry under monotonic racking toad with different levels of precompression is described. The specimens have been constructed with units having 45% perforation and high strength cement mortar. The response, in terms of diagonal strains, was recorded. Rigidity, ultimate diagonal load and mode of failure are reported. To simulate the experimental response, a plane stress linear finite element model has been developed.
