STAAD PROCEDURE for STEEL DESIGN (STEEL FRAME) 1.
Create geometry of the structure -Node / beam member
2.
Specify member properties -Assign member properties -Material constant -Specify member offset
3.
Print member info (Pre-Analysis print)
4.
Specify support
5.
Specify loads -Creating load cases -Associating load to member
6.
Specify the analysis type (Statics Check)
7.
Specify Post analyis print command -Member forces (All) -Support reactions
8.
Shortlisting the load cases (depending on the requirement of specification)
Re-specifying the Analysis Command *When the analysis & design engine executes the member selection operati on we specified in the previous step, a new set of properties will end up being assigned to tho se members. This has the effect of changing the stiffness distribution for the entire structure. Since the structure is statically indeterminate, we ought to re-analyze it if we want the nodal displaceme nts, member forces, etc. to reflect this new stiffness distribution. The command to be generated is hence: -Perform Analysis 11.
Re-specifying the TRACK Command *The final calculation we need to do is make sure the current set of mem ber properties pass the code requirements based on the up-to-date member forces. This will requi re that we do a code checking operation again. To restrict the output produced to a reasonabl e level, we specify the TRACK parameter again as: -TRACK 1 ALL
12.
Re-specifying the CHECK Code Command *The analysis operation carried out in response to the command in Sectio n 1.5.15 will create a new
set of member forces. These forces will very likely be quite different f rom those which were used in the member selection operation (see the commands of section 1.5.14). Consequently, we have to verify that the structure is safely able from the standpoint of the desi gn code requirements to carry these new forces. A code checking operation, which uses the up-todate cross sections of the members, and the latest member forces, will provide us with a status rep ort on this issue. The command to be generated is hence: -CHECK CODE ALL 13.
