Mechanics of Masonry in Compression
Publication: Journal of Structural Engineering
Volume 111, Issue 4
Abstract
Strength and deformation of clay‐unit masonry under uniaxial concentric compressive force were investigated. Biaxial tension‐compression tests of bricks and triaxial compression tests of mortar were done to establish constitutive relations for each material. Mortar strengths and brick types were varied. Interaction effects of these two materials were examined using a theory proposed by others. A numerical model based on this theory was used to compute the force‐deformation relationship for a stack‐bond prism. Results of the analysis were compared with measured strengths and deformations of test prisms. Results of the study indicated that mechanics of clay‐unit masonry in compression could be well represented with a relatively simple model, and the most significant parameter to consider was the dilatant behavior of the mortar.
