Material Button / Materials Screen
This button allows you to define the concrete strength, concrete density, and concrete modulus of elasticity, steel yield strength, and concrete type.

To start, click Material to activate the Materials screen. Input the values in the appropriate fields. Click OK to accept all data and return to the Geometry screen.
Note: Substructure
automatically calculates the elasticity; but these values can be edited
manually. Also, there are three concrete types available in
Substructure: normal, sand-lightweight, and
all-lightweight. There are separate options to specify the steel yield strength
for cap flexure steel, cap shear steel, column steel and footing steel.
