Title: Analysis of Shrinkage and Creep of Composite Beams on Redundant Supports
Author(s): Zdenek P. Bazant
Publication: Special Publication
Appears on pages(s): 373-386
Keywords: axial loads; beams (supports); bending moments; composite construction (concrete and steel); concrete slabs; continuity (structural); creep properties; deformation; girders; reinforced concrete; shrinkage; statically indeterminate structures; strains
Abstract:For the rate-type creep law of concrete (Eq. 1), the general problem of creep analysis is converted to a sequence of elasticity problems with intial strains. It is shown how this general method can be applied to the analysis of composite beams. The method is demostrated by a numerical example. It is found that statical indeterminancy of supports significantly alters the effects of shrinkage in composite beams.
