Abstract
The article presents the derivation of the resolving equations for calculating short eccentrically compressed reinforced concrete elements taking into account the creep of concrete. The case of symmetric reinforcement is considered. A viscoelastoplastic model of hereditary aging by A.G. Tamrazyan is used. Comparison of solutions based on linear and nonlinear creep theory is performed.
Highlights
The second term is the creep deformation that develops in time
I at the moment of time t t are found using the linear approximation:. Such a technique for determining creep deformations is used in works [3,4,5,6,7]
With this creep measure, the creep deformation can be represented as a sum of not five, but only two components [8,9,10]
Summary
We consider a short reinforced concrete rod, which is acted upon by an eccentric force (Fig. 1). Where f [ (t)] – some stress function, С(t, ) – creep measure. The first term on the right-hand side of (1) is the instantaneous deformation, which is the sum of the elastic and plastic components. The second term is the creep deformation that develops in time
