Properties of Creep Compliance Functions and Their Relation to Retardation Spectra
Original language description
This contribution examines how the properties of a viscoelastic model are affected by the choice of the creep compliance function and by the properties of the corresponding continuous retardation spectrum. Attention is paid to the phenomenon called divergence of creep curves, which arises for certain types of models but is questionable or even unacceptable from the physical point of view. Divergence occurs when the distance between creep curves (plotted for different ages at loading as a function of current age) increases, and its consequence is that, if the principle of superposition is accepted, the recovery of strain after unloading becomes non-monotonic. Analysis of this undesirable phenomenon is performed for creep models recommended by major design codes (ACI, CEB, fib, JSCE), and for simple as well as advanced models developed by researchers (DPL, LDPL, B3/B4, GL2000). The ranges of ages at loading and load durations for which divergence occurs are detected and illustrated by gr
