a warping Model korrozionno the damaged reinforced-concrete element in inkrementalnoj to the form
The presented analytical dependences allow to construct a pliability negative mould [Ciy ∙] korrozionno the damaged is long a deformable reinforced-concrete element with cracks. Change in time deformativnyh properties neutralised a§ressivioj environment
Concrete at negative mould formation [Ctyj it is possible to consider change resulted kasatelnogo the module of deformations in time:
Where - dependence of change of the module of deformations of concrete on time
Owing to excited environment impact during the considered moment of time - change factor kasatelnogo the module of strips of concrete between cracks defined on analytical dependences of the description of charts of a warping of the concrete, expressed through levels of deformations ης∣ and pressure//.
Where Eb∖t) - dependence of change of the module of deformations of concrete in time owing to excited environment impact.
For the account of influence of an excited environment on a reinforcing bar it is necessary to define for what interval time an excited environment reaches a reinforcing bar after the beginning of contact of an element with an excited environment. We will designate g - time of neutralisation of a blanket of concrete. Then corrosion losses of sectional view of a reinforcing bar during excited environment impact at formation of a negative mould of a pliability can be considered decrease in a percentage of reinforcement μ (t - τ) owing to a reduction of area of sectional view of a working rod of armature under the formula:
Where-area armatures at a direction falling to unit of length of a characteristic element depending on time of impact of an excited environment
