Analysis of concrete structures subjected to sustained temperature gradients

A simple method using aging coefficients and “creep-transformed” section properties is presented for computing time-dependent effects in uncracked concrete members subjected to sustained loads and sustained temperature gradients. The creep coefficients at elevated temperatures are determined using a normalizing function for temperature. The method is applied to prestressed continuous beams and the results are compared with experimental data. Key words: analysis, concrete (prestressed). concrete (reinforced), creep, loads (forces), shrinkage, structural engineering, temperature.
