Evaluation of Pre-tensioned Prestressed Concrete Beam Behavior by Finite Element Analysis Using ATENA 3D

Abstract

This research involves a numerical study of the nonlinear behavior of pre-tensioned prestressed concrete beams with multiple layers of strand and shear reinforcements under flexural loading. Validation of the model was performed based on the results of the standardized four-point static bending test reported in previous experimental research. The ATENA 3D software could simulate the experimental tests and provide meaningful results. Moreover, it is possible to express the behavior of four-point bending test by using ATENA 3D without attribution on an experimental but based on a validated one model. This saves the effort and cost needed to prepare and conduct the laboratory test.
