In this report, accepted equations for the respective estimation of the known, causally different types of deflection for r. c. beams and one-way slabs are incorporated into the authors' deflection calculation system for two-way floor structures, so as, with it thereby modified, to be of extended and generalized use for these. First in the subsequent efforts the observed longtime proceeding of the deflection of hitherto tested slab models under sustained service loading and some field floor slabs with deflection damages is set against its follow-up prediction by the current modified procedure, as well as its equivalent estimations by the ACI-and CEB-methods as comparative others from building codes. Also, in consideration of the effect of constructional inaccuracies involved in actual specific instances the relative adequacy of the presented procedure is further examinedjwhen, using this again, measured deflections of several pertinently damaged slab examples are reviewed and generally affirmative results are obtained.
