Abstract:
This paper describes the behaviour of reinforced concrete beams and slabs under sustained service loads and outlines reliable techniques for modelling the various factors that affect in-service deflection. The effects of concrete cracking, tension stiffening, creep and shrinkage on cross-sectional stresses and deformation are considered in the modelling, together with the effects of reinforcement quantity and position. The proposed method for deflection calculation is illustrated by example and a comparison between the calculated and measured instantaneous and time-dependent deflections is presented for a reinforced concrete one-way slab subjected to sustained service load.
