| Abstract | Poor seismic performance has been associated with lightly reinforced and unconfined non-rectangular reinforced concrete (RC) walls in recent earthquake events. The non-rectangular C-shaped RC wall is a popular construction choice for providing lateral stiffness to the building while also enclosing a service core, lifts, stairs or toilets. Given that the current provisions of AS 3600:2009 for the design of RC walls require very little (if any) confinement and allow low amounts of distributed longitudinal reinforcement to be used, an investigation is warranted focusing on the seismic performance of such structural elements. This paper presents an overview of some of the research results from an investigation focusing on the seismic performance of RC C-shaped walls with a range of different parameters that would be commonly found in low-to-moderate seismic regions. An extensive number of finite element modelling analyses were undertaken using VecTor3. The equivalent plastic hinge length results from the analyses are discussed and some recommendations for boundary elements of walls are proposed for the next revision of the AS 3600. |
