This study investigates the dynamic response of high-rise structures characterized by irregular shape, emphasizing the influence of shear walls on their seismic performance.Irregular-shaped buildings pose unique challenges in terms of structural behavior and response to dynamic loading, especially under seismic forces.The incorporation of shear walls is a common strategy to enhance the structural integrity and mitigate the adverse effects of lateral forces.The research employs advanced structural analysis techniques, including finite element modelling and dynamic response simulations, to assess the seismic performance of irregular-shaped high-rise building with and without shear walls.The study considers various irregular configurations, such as setbacks, protrusions, and asymmetries, which are common in contemporary architectural designs.Key parameters influencing the dynamic response, such as natural frequencies, mode shapes, and displacement distributions, are thoroughly investigated.The effectiveness of shear walls in reducing building deformations and enhancing lateral stiffness is evaluated under different seismic scenarios.The study also explores the optimal placement and design of shear walls to achieve maximum efficiency in controlling dynamic responses.
