T.3 Specifying Material Constants

When " T.3 Specifying Element Properties ", you used the Material option. Consequently, the material definition (E, Density, Poisson's Ratio, etc.) of concrete were assigned to the plates along with the properties

The STAAD input file commands generated are:

DEFINE MATERIAL START
ISOTROPIC CONCRETE
E 2171.85
POISSON 0.17
DENSITY 2.35616e-005
ALPHA 1e-005
DAMP 0.05
TYPE CONCRETE
STRENGTH FCU 2.7579
END DEFINE MATERIAL
CONSTANTS
MATERIAL CONCRETE ALL

Tip: However, if you had not assigned the material definition along with the thickness, you could use the Materials page in the Analytical Modeling worfklow page control to do so.
