In the paper authors analyze anchorage zones in the simply supported prestressed beams in order to find the most sufficient tensile reinforcement. Using Struts and Ties (ST) and Finite Element Method (FEM) models of pre-tensioned and post-tensioned beams authors examine how the arrangement of tendons in the cross section influence the value of tearing force in the anchorage zones. Two dimensional and three dimensional models are performed and results from different computer programs (Autodesk Robot Structural Analysis Professional 2011 and ABAQUS) are compared. Practical hints for designers are pointed.
