I have defined a number of design parameters in my file but STAAD.Pro does not consider these for design. What could be the reason ?
For the design parameters to be honored in the design process, these parameters should be located ahead of the design command in the input command file. The best way to check that would be to go to the input editor ( Edit > Edit Input Command File ) and check the order in which the commands are written. The following examples show the correct and incorrect locations for the design parameters
Correct location for design parameters ahead of the design command ( CHECK CODE )
CODE AISC UNIFIED 2010
LY 5 MEMB 1 TO 10
LZ 15 MEMB 1 TO 10
UNT 5 MEMB 1 TO 10
CHECK CODE ALL
Incorrect location for design parameters after the design command ( CHECK CODE ) – design will not honor these
Although the above example relates to steel design and the US design code but the same is true for Concrete Design as well as ALL international design codes.
