During the SIG session this morning someone was asking about the Tau-b reporting. Just wanted to mention that information on Tau-b are printed as part of the analysis output file. If such messages are not required to be printed, one can turn those off…

There might not be anything wrong with your model, this just happens under some circumstances. There is a fairly lengthy explanation of how this check is performed in the manual Section 3.2.1 AISC 360 (ASD and LRFD) and beyond, and I see you’ve already…

Exactly, the displacement i have compared are the nodal displacement to check the drift of the structure. Is it possible to get the displacement of the nodes with full EI after analysis to check the serviceability (drift) limits, i believe that the reduced…

I am getting the same displacement by changing the REDUCEDEI also, please refer to the below and advice, The displacement results shows that the full EI is used for calculating the deflections? please advice The below results with command, PERFORM…

While using the REDUCEDEI 1 or 0, there is no change in the deflection values (i.e. getting the same deflection values while running with REDUCEDEI 0 or 1 ), please advice (may i assume that the deflections are calculated with full EI in all the cases…

So as to be of a little more immediate help to your question regarding using the Direct Analysis: 5.37.5 DIRECT Analysis (Available effective STAAD.Pro 2007 Build 03) General format: PERFORM DIRECT ANALYSIS ( {LRFD or ASD} TAUtol f1…
