Prediction of Creep Deformation in Concrete Using Some Design Code Models

Abstract

The tendency of a concrete material to deform under stress is often responsible for excessive deflection at service loads which can compromise the performance of elements with a structure. Hence, the realistic prediction of both the magnitude and rate of creep strain is an important requirement of the design process. Therefore, relatively simple empirically based national design Code models are analyzed in order to predict the magnitude of creep strain. The models assessed are ACI 209 (1992), AS 3600 (1988), BS 8110 (1985), CEB-FIP (1978), CEB-FIP (1990), SAB 0100 (1992) and the RILEM Model B3 (1995). (English) [ABSTRACT FROM AUTHOR]
