Three-dimensional model of a prestressed tie
Abstract
Basic notions of numerical modelling of prestressed ties, as used in the analysis of spatial prestressed reinforced-concrete structures, are presented. The ties are modelled by one-dimensional curvilinear elements contained in a three-dimensional finite element of concrete. The model developed in this way is entered in the PRECON3D program. The use of the model is presented through numerical examples, and its validity is checked by comparing the results with numerical and experimental results taken from literature.
