| Abstract | Using the lattice model, nonlinear incremental analysis has been performed to capture the ultimate strength and deformation ability of concrete piers after the yielding of longitudinal reinforcement. The changes in shear resisting mechanism of cantilever concrete piers subjected to monotonic loading are clarified during, for instance, the initiation of diagonal cracking, the yielding of longitudinal reinforcement and the crushing of concrete. The focused parameters in this research are shear reinforcement ratio and the size of concrete piers. These two parameters are concerned to see how they affect the ultimate failure state after the longitudinal reinforcement is yielded. The verification of the lattice model is examined by past experimental data and conventional flexural theory. The study indicates that shear reinforcement ratio makes an important role to enhance the ultimate ductility. On the other hand, the ductility factor at ultimate failure is insensitive to the size effect of concrete pier. After checking the applicability of the lattice model, the investigation on safety of highway piers of Hanshin Expressway is numerically evaluated. |
