Assessing the structural behavior of shear-critical prestressed concrete beams using finite element analysis and digital image correlation KU Leuven
The reported study firstly presents the results of an extensive experimental program consisting of 9 full-scale I-shaped prestressed concrete beams. Each specimen is subjected to a four-point bending test with monotonically increasing load until failure occurs. The investigated parameters are the amount of prestressing, the amount of longitudinal and shear reinforcement and the shear spanto- effective depth ratio respectively. Continuous ...
