TLDR
In this article, a simple design oriented procedure for the control of deflection in reinforced concrete slab systems is proposed, and a rational expression for the maximum allowable span to depth ratio for beams, proposed recently by Rangan, is extended to include the entire range of reinforced concrete flexural members, including two-way edge-supported slabs, flat slabs and flat plates.Abstract:
A simple, design oriented procedure for the control of deflection in reinforced concrete slab systems is proposed. A rational expression for the maximum allowable span to depth ratio for beams, proposed recently by Rangan, is extended to include the entire range of reinforced concrete flexural members, including two-way edge-supported slabs, flat slabs and flat plates. The data used for the calibration of the procedure was obtained from an extensive series of computer experiments with reinforced concrete slabs using a non-linear, finite element model. The techniques are illustrated by example and a comparison with available field measurements of in-service slabs in made. (Author/TRRL)read more

Prediction of time-dependent deformations in post-tensioned concrete suspended beams and slabs in tall buildings
TL;DR: In this paper, the authors proposed a method to predict deflection in reinforced or prestressed concrete flexural members during their lifetime, and demonstrated that prediction of deflection can be extremely computationally difficult.
