STRESS ANALYSIS FOR CONCRETE INCLUDING VISCOELASTIC RESPONSE.

Abstract

Experimental data concerning creep of concrete are analyzed and the two traditional ways of representing creep characteristics; rheological models and mathematical formulas are compared to the experimental results. Models are fully practical when certain restrictions are imposed in the time-variation of the loading. Some problems of structures of reinforced concrete are studied and the analogue principle is extended to them. When a general load acts on a concrete structure, an expression which includes the aging effect is needed. Some problems of this category are studied concerning one- and two-dimensional bodies. Particular emphasis is given to stability. A phenomenological interpretation of the role of temperature is proposed. (Author)
