D2.B.6 Material Properties
For specification of material properties, the user can use either:
- built-in material constants
- user-defined materials
Refer TR.26.2 メンバーとエレメントに対する定数の設定 for further information on the Built-in Material Constants feature.
Refer TR.26.1 材料の定義 for further information on the Define Material feature.
D2.B.6.1 Young’s Modulus of Elasticity (E)
STAAD.Pro’s default steel material’s E value is 205,000 MPa. However AS 4100 section 1.4 states that the modulus of elasticity should be taken as 200,000 MPa. There are a number of options to change this value:
- change the steel material through the input file or GUI for each file created
- define a new steel material for each file created
-
change the default STAAD.Pro metric E value in the file C:/Windows/StaadPro20070.ini, going to the [Material-Metric] section, and changing E1=205.0e6 to E1=200.0e6. Restart STAAD.Pro for this to take effect.
