Code: Select a corresponding concrete design standard for considering the change of modulus of elasticity. This option is active
DB: Select a concrete type recognized in each of the standard codes.
Type of Design = "SRC"
Enter the material properties for steel and concrete in the Steel and Concrete entry windows similar to the above Type = 'Steel', 'Concrete' cases.
Type of Design = "User Defined"
Select when the material type is not 'Steel', 'RC' or 'SRC', or when the user wishes to define the material properties directly.
Orthotropic material properties can be also defined in ECS. User Defined materials are not used in Design.
Modulus of Elasticity
Poisson's Ratio
Poisson's ratio is used to calculate the Shear Modulus of Elasticity.
Thermal Coefficient
Thermal Coefficient for thermal stress analysis.
Celsius
Fahr
Weight Density
Use Weight Density to calculate self-weights and masses.
Shear Modulus: Shear Modulus of Elasticity(Local-xy, Local-xz, Local-yz)
Shear Modulus of Elasticity = Modulus of Elasticity / (2 x (1+Poisson's ratio))
Note
For Type of Material = Isotropic, Shear Modulus is calculated by the above expression. For Type of Material = Orthotropic, the user defines the values of shear modulii.
Use Mass Density: Mass per unit volume.
Note
If "Use Mass Density" is checked, Mass Density is calculated using the acceleration of gravity(g) given in the DB. If "Use Mass Density" is unchecked, Mass Density is calculated using the acceleration of gravity(g) specified in Model>Structure Type. The Mass is separate from Dead Load and used for eigenvalue analysis only.
Plasticity Data
Enter plastic material data.
Plastic Material Name: Select a Plastic Material whose plastic model properties have been defined in the Plastic Material dialog box.
Inelastic Material Properties for Fiber Model & Non-dissipative element
The selected Inelastic Material Models are used for Fiber Model analysis and Non-dissipative element design.
Concrete: Select an inelastic Material for concrete. Click the ... button to create or modify the model data.
Rebar: Select an inelastic Material for rebar. Click the ... button to create or modify the model data
Confined Concrete for columns: Select the concrete material for the area confined by the hoop.

Damping ratio
Define the damping ratio by materials.
Note 1
Apply different damping ratios to concrete and steel for response spectrum analysis / time history analysis.
- Response Spectrum Analysis : When Strain Energy Damping is selected, the damping ratios can be defined by materials.
- Time History Analysis : When Strain Energy Damping or Element Mass & Stiffness Proportional is selected, the damping ratios can be defined by materials.
Note 2
The default damping ratios for each material are:
- Steel : 0.02 (2%)
- Concrete / SRC : 0.05 (5%)
- USER : 0.00 (0%)
