Parabolic masonry model- mas_par

This is a uniaxial trilinear material model for masonry that is based on the hysteretic rules of the con_ma typical constant confinement concrete model .

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

Mean Compressive strength – f_c
The default value is 3500 KPa.

Mean Tensile strength – f_t
The default value is 150 KPa.

Modulus of Elasticity – Ec
The default value is 1.05E+07 KPa.

Poisson Ratio
The default value is 0.20.

Strain at peak stress – ε_c
The default value is 0.002.

Descending branch parameter
The default value is 1.00.

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