A New Proposed Model to Estimate Compressive Strength of Brick Masonry Prisms

Abstract:

This study presents a new model to estimate the compressive strength of masonry prisms considering both crashing and splitting failure mechanisms of the masonry prisms. The model is developed considering a probability of events by defining the resulted failure of the masonry prism as the main event. On the other hand, the different modes of failure including crushing of brick units, crushing of mortar under compression stresses and splitting of the brick units and mortar under bilateral stresses have defined as sub-events of the resulted failure. Eventuaaly, the developed model is verified against extensive results of experimental tests of masonry prisms that published by other researchers. A comparison is conducted between the estimated strength and the experimental results as well as those obtained from several available models in term of statistical measures. Comparison results reveal that the new proposed equation exhibits very good agreement with experimental results and shows the best accurate estimations with less deviations compared with the other available equations. The new proposed equation shows a mean value of the experimental to the estimated compressive strength of masonry equals to 1.01 ± 0.35 and a coefficient of variations equals to 35.12 %.
