Aug 01, 2010  It is generally accepted that the mechanical behaviour of a FRP-confined concrete member under load depends on the stress strain relationship of the constituent materials (i.e. FRP and concrete). The stress strain relationship of concrete under load is time-dependant and affected by factors including ambient condition, creep, damage (at high ...

such as the drying creep effect. Further nonlinear behavior, due mainly to gradual microcracking, appears in high-stress creep. The solution of the creep and shrinkage of a concrete body depends on the solution of the macroscopic water diffusion through the body (drying or wetting), but the reverse coupling of these problems is negligible.

Creep and shrinkage of concrete - Wikipedia

Creep and shrinkage of concrete are two physical properties of concrete.The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers. Unlike the creep of metals, it occurs at all stress levels and, within the service stress ...
