For structural and crack predictions, virtual work principles was used to estimate (a) transient strains due to the concrete creep and shrinkage, (b) the resulting timedependent stress redistribution, as well as (c) the displacement variations in the frames and finally (d) the pre-stressing losses in the high yield tendons. The concrete shear stresses have been evaluated by the principle of Juravskiy. The need to validate the numerical results, required a series of controlled experiments supporting the evaluations at (a) to (d), in addition to (e) calibrating the parameters of the pre-stressing losses, (f) predicting the portal frames sections’ stiffness and strength by determining the flexural and nonlinear creep capacity of the frames’ sections and hence, (g) devising a definition for structural durability and integrity, with regards to concrete stress-strain relationship under sustained service loads.
