Trilinear masonry model- mas_tl

This is a simplified uniaxial trilinear material model that assumes no resistance to tension and features a residual strength plateau.

Five model-calibrating parameters must be defined in order to fully describe the mechanical characteristics of the material:

Mean Compressive strength – f_c1
The default value is 5000 KPa.

Initial stiffness – E₁
The default value is 1.05E+07 KPa.

Post-peak stiffness – E2
The default value is -1.00E+07 KPa.

Residual strength – f_c2
The default value is 1000 KPa.

Specific weight -
This is the specific weight of the material. The default value is 24 kN/m3.
