Resumen
Within the hypothetical context of a model for a set of data obtained from a long-term stiffness test on GRP test pieces, the objective of this document is to produce explicit formulae for: a) estimating all four parameters in the model, i.e. a, b, c and d, and b) calculating confidence and prediction intervals about the curve. These formulae are presented in this annex, along with associated graphical displays for a typical data set. NOTE While the data and procedures refer to a long-term stiffness test, the method can also be applied to data which fit the mathematical model and require extrapolation to 50 years.
