Composite steel and concrete high-rise building under the seismic action

Abstract

Title: A parametric study on influence of tuned mass damper on composite steel and concrete high-rise building under the seismic action.

This thesis explores the seismic resilience of tall steel-concrete composite buildings, with a primary focus on incorporating Tuned Mass Dampers (TMD) as a strategic measure. Given the critical importance of safety and functionality in seismic-prone regions, this research aims to advance our comprehension of effective design strategies.

The research journey commences by examining the structural systems and seismic damping methods employed in high-rise buildings. It highlights the integration of TMDs with steel-concrete composite core outrigger systems, showcasing their collaborative efficacy against seismic forces. Employing a comprehensive approach involving analytical modelling, numerical simulations, and practical case studies, the study compares numerical models with and without TMD systems to determine optimal characteristics and placement for maximum effectiveness.

The practical implications of this research are particularly relevant for stakeholders in high-rise construction. Insights derived from optimization strategies and design considerations contribute to the fundamental understanding, ultimately enhancing the safety and functionality of structures in regions prone to seismic activity. Additionally, the research findings play a crucial role in shaping the development of building standards and regulatory frameworks. The alignment of seismic design standards with cutting-edge advancements in structural engineering is a key objective, aiming to influence the future of resilient high-rise construction.

In summary, this thesis serves as a comprehensive guide for advancing the seismic resilience of steel-concrete composite high-rise buildings. The integration of Tuned Mass Dampers emerges as a tangible and effective solution, poised to enhance both the safety and performance of structures in areas susceptible to seismic activity.
