The Material sheet in the AllCommon.xls workbook defines materials and material grades for structural members. You must define materials and material grades before you can place members or define member types.

When you bulk load this sheet in Delete and Replace mode, you must also bulk load the Permissible Duct Thickness rule.

Material Type

Specifies the material type. For example, type Steel- Carbon or Concrete. The combination of the Material Type and Material Grade columns must be unique.

Material Grade

Specifies the material grade. For example, type A36 or Eh42. The combination of the Material Type and Material Grade columns must be unique.

Density

Specifies the mass or weight density of the material. For example, type 7800 kg/m3. Any positive real value is valid. Zero is also valid.

Max Tension

Specifies the maximum allowable tensile stress for the material. Any positive real value is valid.

Yield Stress

Specifies the yield stress for the material. Any positive real value is valid.

Elastic Modulus

Specifies Young's modulus (the modulus of elasticity) for the material. Any real value greater than zero is valid.

Poisson Ratio

Specifies Poisson's Ratio for the material. Any real value greater than or equal to zero and less than 0.5 is valid.

Shear Modulus

Specifies the shear modulus of elasticity for the material. Any real value greater than zero is valid.

Therm Exp Coeff

Specifies the coefficient of thermal expansion for the material. Any positive real value is valid. Zero is also valid.

Max Compression

Specifies the maximum allowable compressive stress for the material. Any positive real value is valid.

Max Shear

Specifies the maximum allowable shear stress for the material. Any positive real value is valid.

Ultimate Stress

Specifies the ultimate stress for the material. Any positive real value is valid.

Damping Coeff

Specifies the damping coefficient for the material. The damping coefficient is used in dynamic analysis. Any positive real value is valid.

Specific Heat

Specifies the specific heat for the material.

Thermal Cond

Specifies the thermal conductivity for the material.

Emissivity

Specifies the emissivity for the material.
