The postprocessing mode is inactive as you have the command SET GUI 1 in the file. If you take that command out you would be able to access the postprocessing mode. Additional observation: The PERFORM ANALYSIS and CHANGE commands after load cases 9…

You can do that by using a GENERATE command. More details can be found in these Forum discussions: communities.bentley.com/.../386387 communities.bentley.com/.../386365

The fire proofing is not going to account for any additional stiffness. The following wiki has suggestions on how to model encased sections http://communities.bentley.com/products/structural/structural_analysis___design/w/structural_analysis_and_design__wiki…

You can go to Surface Forces at Y (Local) tab inside the Surface Results table and look at the FXY ( shear force ), FY ( vertical force) and Mz ( in-plane moment). Please refer to section 1.6.3 of the Technical Reference Manual titled Surface Element…

Just for future reference. A couple of wikis on the same topic can be found at communities.bentley.com/.../31879.direct-analysis-and-member-tension communities.bentley.com/.../32145.direct-analysis-with-inactive-members

I created an example demonstrating how you can use INACTIVE MEMBER specification in conjunction with DIRECT ANALYSIS. Hope this helps. Direct_Analysis_with_Inactive_Members.STD

PDELTA ANALYSIS would just do one iteration of pdelta whereas the PDELTA nn ANALYSIS would do "nn" number of iterations of pdelta. The nn stands for the number of iterations. In other words PDELTA 30 ANALYSIS would do 30 iterations. It is always advisable…

There is no way to run a DIRECT ANALYSIS with MEMBER TENSION. You can do one of the following Option 1 Do a DIRECT ANALYSIS with these members specified as TRUSS members. Check the member forces to find out for which load cases the axial forces in…

Gilbert : As of now, STAAD.Pro does not allow Tension/Compression members to be used in a DIRECT ANALYSIS. If TENSION/COMPRESSION is assigned, these attributes are turned off and the members are simply treated as TRUSS members which can take both tension…

Use the TRACK 1 parameter and you will have a much detailed output for all composite members with critical loads. A TRACK 2 will print an even more detailed output.

There are few overlapping plates in the model that you can check by going to Tools > Check Improperly Connected Plates. Also check the beam plate connectivity by going to Tools > Check Beam Plate Connectivity. The slabs defined as plates would contribute…

The analysis output file only reports the accidental eccentricity but the dynamic eccentricity (DEC ) is not reported which can be confusing. However the analysis does automatically consider the torsion from the dynamic eccentricity along with the accidental…

The edge reinforcements are reported as number of bars of certain size. The software does not tell you how to provide these bars and so you can arrange the bars close to the edges after allowing for adequate clear cover. You may refer to any detailing…

At nodes 134, 201, 203 & 205 you applied full releases to beams framing in from both directions. The continuous beams ( 177, 429 … ) should not have releases within the span. Also you should avoid releasing MX when applying member releases as that allows…

For defining cables which would serve as braces in tension, it should be enough to specify these as MEMBER TENSION. You do not need to define these as cables as such. The cross section can be defined using the Define option within the Property - Whole…
