Investigation of the influence of open straight-legged stirrups on the shear resistance of concrete beams: Nonlinear finite element analysis

Nowadays, Rijkswaterstaat reassesses many older concrete bridges to guarantee their structural safety under the influence of increased traffic loads and stricter standards. Many of these concrete bridges contain open straight-legged stirrups, which are not allowed to take into account for the calculations of the shear resistance according to...

Towards a uniform and optimal approach for safe NLFEA of reinforced concrete beams: Quantification of the accuracy of multiple solution strategies using a large number of samples

Application of Nonlinear Finite Element Analysis (NLFEA) is lagging behind the many digital advances in the structural engineering practice. This is due to the need for codes and standards. To help development of these codes and standards, 119 solution strategies were developed with different assumptions and choices for the concrete constitutive...
