5.26 Specifying and Assigning Material
Constants
Purpose
Material constants are attributes like Modulus of Elasticity and
Density which are required for operations like generating the
stiffness matrix, computing selfweight, and for steel and concrete
design.
In STAAD, there are 2 ways in which this data may be specified :
a.
a 2-step process that involves
step 1 - Creating the material data by defining MATERIAL
tags specified under the heading DEFINE MATERIAL (see
Section 5.26.1)
step 2 - Assigning them to individual members, plates and
solids under the heading CONSTANTS (see Section
5.26.2)
This will create commands as shown below :
DEFINE MATERIAL
... name
... <-------------- Part 1
...
END MATERIAL
CONSTANTS
MATERIAL name ... <-------------- Part 2
