Title: Time-Dependent Effects in Composite Concrete Beams
Author(s): Dan E. Branson-F
Publication: Journal Proceedings
Appears on pages(s): 213-230
Abstract:The effects of direct shrinkage and creep deformation and differential shrinkage in composite concrete beams are discussed. Two different methods for determining differential shrinkage stresses and deflections are briefly summarized and compared. Procedures for predicting the total (initial plus time-dependent) deflection of shored and unshored composite beams, in which the precast beams are either reinforced or prestressed, are discussed. Also included is a discussion of existing experimental data dealing with the time-dependent behavior of composite concrete beams.
