Review-Dynamic Analysis of Symmetrical & Unsymmetrical High Rise Structure with Curtailed Shear Wall

Abstract

This review paper investigates the dynamic analysis of symmetrical and unsymmetrical high-rise buildings with curtailed shear
walls, focusing on key parameters such as axial force, node displacement, and base shear. Symmetrical structures, with their uniform mass and stiffness distribution, offer predictable dynamic responses, whereas unsymmetrical structures, characterized by irregularities in geometry, mass, or stiffness, pose significant challenges due to torsional effects. Curtailing shear walls—reducing their height to optimize material usage and architectural flexibility—further complicates these analyses. Through an extensive review of analytical and experimental studies, this paper highlights the influence of curtailed shear walls on the aforementioned parameters. Findings indicate that while curtailed shear walls can reduce construction costs and enhance architectural freedom, they also lead to increased node displacements, altered axial force distributions, and reduced base shear capacity, particularly in unsymmetrical structures.
