In a DIRECT ANALYSIS, are the deflections for serviceability checks computed using the unreduced E and I values ?
By default STAAD uses the reduced E and I for calculating displacements. However in the section 5.37.5 of the Technical Reference Manual ( titled Direct Analysis ), you will find mention of a parameter named REDUCEDEI which can be set to a value of 0, for the full E and I to be considered for computing section displacements.
