    Abstract

    The results of a two-phase experimental research program to develop an ultimate flexural strength theory for reinforced brick masonry is reported. Twenty beam-column specimens and corresponding prisms were tested to determine the flexural compressive stress distribution for high and low strength brick masonry constructed with Type S portland cement lime mortar with loading both parallel and perpendicular to the bed joints. This data established the parameters for defining an ultimate compressive stress block for brick masonry. Reinforced brick masonry beam tests (still in progress) have determined the applicability of the developed theory to reinforced flexural elements. Results show that (1) the ultimate compressive stress-strain relationship for brick masonry under flexural loading and axial loading are different; (2) there is a correlation between the ultimate flexural compressive strain and prism strength; and (3) an ultimate strength theory reasonably predicts the capacity of reinforced brick masonry beams.
