Plastic Hinge Length for Lightly Reinforced C-Shaped Concrete Walls
This research investigates the equivalent plastic hinge length of reinforced concrete C-shaped walls with reinforcement detailing typically found in low-to-moderate seismic regions. Reinforced concrete walls in these regions commonly have low amounts of longitudinal reinforcement and unconfined boundary regions, which have been shown to perform poorly in recent earthquake events. A series of state-of-the-art finite element analyses are undertaken to find the longitudinal strain distributions of low-rise, mid-rise, and high-rise C-shaped walls. The results of the equivalent plastic hinge lengths from the numerical investigation are shown to compare poorly to the predictions from some of the equations that currently exist in the literature. Subsequently, expressions are derived for the equivalent plastic hinge length for these types of walls and for the different modes of bending. The expressions derived from this research intend to improve the displacement capacity for these types of walls when using plastic hinge analyses.
