Masonry

The Masonry material model is a material model that simulates the behavior of the Masonry wall under lateral load using homogenization techniques. First, homogenize the brick and the head joint, and then homogenize the homogenized material and the bed joint to obtain the physical properties of the entire homogenized material. In the masonry material, tensile cracking is considered to be the only nonlinearity. Cracks can occur on both bricks and on two joints. In the event of a crack, the elastic modulus of the crack is reduced by a predetermined proportion. Then, the newly homogenized material is obtained by reflecting the reduced elastic modulus. The assumptions applicable to the Masonry Model are as follows.

1. Brick has linear elastic behavior and brittle failure occurs.

2. Mortar behaves linear elastically.

3. Brick and mortar are perfectly bonded.

4. Head joints are continuous.
