| 要旨 | After retrofitting of RC piers of an elevated π-shaped expressway, a subsequent assessment of the overall double column bents left doubts that some of the un-retrofitted parts might experience undesirable failures that might prohibit achieving the target ductility. Consequently, an experimental program, where quantity of shear reinforcement of RC beams was the experimental variable, was conducted. Furthermore, a numerical analysis was performed to check applicability of the finite element technique. Overall behavior, damage propagation, failure mechanism and modes were investigated. Appropriate strengthening for the RC beams should be employed to ensure better performance during future earthquakes. |
