LONG-TERM DEFLECTIONS OF REINFORCED CONCRETE BEAMS

A study is made of the factors affecting long-term deflections in reinforced concrete beams. The study is based on a theoretical analysis of creep and shrinkage effects in a rectangular section containing both tension and compression reinforcement and subjected to a constant sustained moment. Equations are derived which can be used to evaluate long-term deflection multiplying factors for reinforced concrete flexural members.
