T.2 User-defined concrete material

The STAAD input file commands generated are:

DEFINE MATERIAL START

E 22
POISSON 0.17
DENSITY 1.9e-008
TYPE CONCRETE
STRENGTH RY 1 RT 1 FCU 0.025
END DEFINE MATERIAL

You will create a material definition for a lightweight concrete to use for all members.

「解析モデリング」ページコントロールバーで「材料」ページを選択します。
「材料 - 全体の構造」ダイアログおよび「材料」テーブルが開きます。
「材料 - 全体の構造」ダイアログの「等方性」タブで、「作成」をクリックします。
「等方性材料」ダイアログが開きます。
Input the required, user-defined material values for a lightweight concrete:
1. Type CONCRETE-LTW in the Title field.
2. Type 22 in the Young's Modulus (E) field.
3. Type 0.17 in the Poisson's Ratio (nu) field.
4. Type 1.9e-008 in the Density field.
5. Select CONCRETE from Type of Material drop-down list.
6. Type 0.025 in the Compressive strength (Fcu) field.
Leave the remaining property fields as zero for this tutorial exercise. The shear modulus is calculated based on E and Poisson's ratio and the thermal coefficient and critical damping default to zero. Refer to the TR.26.1 材料の定義 for details.

Tip: The material definition can be edited later by selecting the material in the isotropic materials list and clicking Edit.
The new material is added to the Material table and the list of isotropic materials.
