This book presents a focused and analytically rich study of steel structures and reinforced concrete design in seismic environments, emphasising structural behaviour under dynamic loading conditions. It explores how engineered systems respond to seismic forces, highlighting the importance of ductility, energy dissipation, and structural integrity in resisting earthquake-induced stresses. The book adopts a design-oriented perspective, combining conceptual understanding with practical considerations relevant to modern construction. It examines the role of material properties, connection detailing, and structural configurations in achieving resilient performance. In addition, it considers analytical approaches used to evaluate structural response, enabling engineers to make informed and reliable design decisions. The discussion reflects evolving practices in earthquake-resistant engineering, encouraging a balanced approach to safety, performance, and long-term durability in challenging environmental conditions.

This book is intended for civil engineers, designers, and advanced learners engaged in structural analysis and seismic design. It facilitates the development of critical thinking, technical precision, and practical competence required for constructing safe and resilient infrastructure in earthquake-prone regions.
