Analysis of Reinforced Concrete Shear Walls Using Elastic–Plastic-Damage Modelling
Shear walls are useful structural tools in redistributing the stresses and controlling the damage in reinforced concrete buildings under earthquake loads. Due to their comparatively large cross-sections, they carry significant portion of the base bending moment and shear under lateral load. Analysis of shear walls requires incorporation of inelastic material models as often the stresses the elastic threshold under extreme lateral loading such as earthquake. On the other hand, analysis and design tools used for buildings often employ beam-type 1D finite element formulations for shear walls as well as beams and columns as such models are computationally faster which is especially important in nonlinear time-history analysis and the results are easier to interpret for design purposes. In 1D finite element formulations often uniaxial material models are used. In this study we have employed a multi-axial concrete model within a 1D finite element formulation so that effect of shear stresses can be considered in the material behaviour. The accuracy of the proposed numerical approach is illustrated by comparing its predictions with experimental results from literature.
