Accurate Approximations of Concrete Creep Compliance Functions Based on Continuous Retardation Spectra
Original language description
This paper presents a detailed analysis of the continuous retardation spectra corresponding to a number of concrete creep models stipulated by various codes and recommendations. Approximations of various orders based on the Post-Widder formula are constructed, and the accuracy of the corresponding Dirichlet series approximating the compliance function is assessed. It is shown that the accuracy can often be substantially increased by appropriate modifications of the discrete retardation times used by theDirichlet series. Practical hints regarding the choice of the discrete retardation times and the order of integration used in the evaluation of the compliance coefficients are provided.
