Finite Element Analysis of Self-centering Reinforced Concrete Shear Walls

Abstract Post-tensioned precast concrete walls are an attractive research trend in structural engineering, which replaces cast-in-place earthquake-prone buildings. Precast use mild steel and high-strength post-tensioning for flexural resistance. Mild reinforcement yields tension compression, dissipating inelastic energy. Unbounded tendons used inside the wall to give self-centering capability, lowers residual displacements. At wall-foundation, horizontal slots installed equally. Meanwhile, middle-wall is still anchored base. A three-dimensional finite element (FE) model developed this study assess lateral load response of shear with bottom slots. The seismic performance three distinct evaluated using Abaqus software FEA. validated by comparing experimental data accessible literature. Furthermore, we investigate effects slit length, strand position, initial prestressing level, strength. All these criteria critical constructing structures new concept. results show that accurately predicts all above-mentioned properties, including force–displacement toe area damage walls.
