With regard to the micro-modeling of masonry-filled walls in Diana software, when using simplified micro-modeling, the interface unit is used in the masonry model, there are several problems:
1. Which material is better to choose, Coulom friction or discrete fracture or other? For example, when using Coulom friction, is there a good empirical value or formula for calculating the normal stiffness modulus, shear stiffness modulus and cohesion, friction angle, expansion angle, etc.?
2. For the value relationship between bed-joint and head-joint in the model, how to determine the value of head-joint through bed-joint, and how to determine the value of the interface unit between the filled wall and the frame
Is this a reasonable literature reference? Please help.
