I have a model in which steel design is performed as per AISC 360-16.  Why is it that when I go into Post Processing I only see results for some of the members and not all of them?

 

If you run into this issue you likely have a model containing multiple CHECK CODE commands.  To clarify, the AISC 360-16 code has been enhance so multiple design sets can be viewed/compared in Post Processing, as described in the following excerpt from the STAAD.pro Help Manual:

"If an input file contains multiple parameter blocks (steel design parameter sets) or multiple design commands (steel code check or member selections) within a single parameter block, then the results are available in the Postprocessing workflow. Parameter sets are numbered and multiple design commands in the same parameter block are given as decimals."

This means you could have, for example, two CHECK CODE ALL commands in a model-the first corresponding to PARAMETER 1 in which certain design parameters are specified, and the second corresponding to PARAMETER 2 in which different design parameters are specified.  When the analysis is run you can go into Post Processing and compare the two as desired using the Design Parameters menu under the Results tab to toggle back and forth.  

This comparison is possible even if you don't have multiple parameter blocks.  Suppose your model just has PARAMETER 1, but you have still decided to break up your steel design into separate code checks.  So, instead of the command CHECK CODE ALL you have something like this:

CHECK CODE MEMB 1 TO 100

CHECK CODE MEMB 101 TO 200

CHECK CODE MEMB 201 TO 300

CHECK CODE MEMB 301 TO 400

CHECK CODE MEMB 401 TO 500

CHECK CODE MEMB 501 TO 600

When you go into Post Processing the Design Parameters menu under the Results tab will read Parameter 1, Parameter 1.1, Parameter 1.2 etc.  By default Parameter 1 will be chosen meaning you'll only see the results for members 1 to 100.  You can switch to Parameter 1.1 to see the results for members 101 to 200, Parameter 1.2 to see the results for members 201 to 300, and so on.  If you wish to see the results for all the members, you must chose Maximum as shown below:
