Abstract Solid slabs with drop panels or beams are idealized as horizontal grid of rigidly connected short prismatic members, subjected to gravity loads, and prestressing forces. Creep and shrinkage of concrete and relaxation of prestressing reinforcement are considered. The effect of transient loading inducing cracking on long‐term deflection is accounted for. The analysis follows CEB‐FIP Model Code 2010.
