Sažetak
This paper presents some aspects of the two-dimensional and/or three-dimensional numerical modelling of the reinforced and prestressed concrete structures. The curved prestressing tendons and reinforcing bars, which are modelled by one-dimensional finite elements, are embedded into adequate two-dimensional and three-dimensional finite elements. The influence of the prestressing tendons on the concrete is modelled by distributed normal and tangential forces along the tendons and two concentrated forces at the anchors. The computation of the post-tensioned prestressed structures is organized in three phases: before, during and after prestressing of the tendons. Three numerical examples taken from the literature with known analytical and/or numerical results are given to compare the results obtained by the proposed numerical modelling.
