The article presents three-dimensional finite element modeling method for steel-reinforced concrete penstocks. In the models the allowance is made for the actual material properties manifested upon concrete cracking.
The topical problem of developing adequately fitting mathematical models and analysis of stress-strain distribution in structures with deformational anisotropy was solved. The modeling of metal sheathing, reinforcement and fractured concrete was made.
Analysis of computational results justified the design decisions. Recommendations on maintenance the penstocks were given.
