As far as I know, there is direct provision in STAAD Pro for estimating the long term deflection of a beam. Long term deflection calculation requires the section to be considered as a cracked section, for which an effective moment of inertia(which is in the range of Icr to Igross) is a function of cracked moment and service moment. However, Bentley systems has another structural design tool called RAM Concept, in which the long term deflection calculation for slabs and mat foundations is incorporated.
