Advancement in Modeling of RC Shear Walls

Abstract eng:
Reinforced concrete (RC) shear walls are considered as effective lateral force resisting system that has been widely used in the last decades. RC walls can provide the required lateral stiffness and strength for resisting the lateral loads due to wind or earthquakes. Hence, several experimental and analytical studies were conducted to investigate the behaviour of RC shear walls under the lateral loads in order to enable the designers to predict their seismic response in a building when subjected to a severe ground motion. Predicting the behaviour of RC walls under lateral loads requires enhanced numerical tools that are calibrated using controlled experimental tests. These tools should take into account most of the important factors that could affect the response of RC walls. Hence, modeling of RC walls involves several challenges in representing the combined effects of moment, shear and axial forces, in addition to bar slip, buckling, damping, boundary conditions, as well as rehabilitation method, if any. This paper presents different modeling techniques that have been used by researchers in modeling of RC shear walls. These range from macro-models such as lumped plasticity, multi-axial spring models, combined models, up to micro-models such as finite element models and fibre models. The paper discusses the efficiency of each model in representing both the global and local behaviour of RC shear walls. The objective of this paper is to provide a state-of-the-art on the recent advancements and challenges in the area of modeling of RC shear walls.
