Cameron J. Graham and Andrew Scanlon
The effect of construction loading on deflection of flat plate slabs is investigated. Progressive cracking, as load is incremented to the shored slab, is included in the finite element analysis for instantaneous deflections. Individual creep curves that reflect the loading age of concrete are superimposed to obtain total creep deflections. Overall long-time deflections also include shrinkage effects. Results calculated for a multistory flat plate structure are in good agreement with a set of measured one-year deflections.

This report summarizes available methods for calcu-lating deflections of reinforced concrete beams subjected to temperature change. Selection of design temperatures and temper-ature gradients is discussed as well as the effects of cracking on response in the service load range.

Load-deflection response of prestressed concrete beams with web openings is determined analytically by means of a truss model that includes the effects of progressive cracking. Post-cracking response is based on application of the effective moment of inertia concept. Good agreement between analytical results and experimental results in the service load range is indicated.
