    This textbook covers the collision of a moving, falling or flying object on a rigid barrier or a structural element, and the transmission of the transient action to the rest of the structural system. It is the only up-to-date book on this under-researched topic that confronts engineers on a day-to-day basis.

    The book deals with a range of real-life engineering problems and focuses on the application of knowledge and skillsets from structural analysis and structural dynamics. Fundamental principles and concepts on structural collision are first introduced, followed by their specific applications such as vehicular collision on bridge structures, boulder impact on rockfall barriers and collision by hail and windborne debris. Analytical solutions provided are in the form of closed-form expressions, which can be directly adopted in conventional manual calculations. The use of spreadsheets to simulate the dynamic response behaviour is also covered.

    • The only standalone book covering the topic from a civil engineering perspective
    • Practical guidance on real-life engineering problems, and use of computational and physical methods
    • Conveys methodology validated experimentally

    The book provides an excellent guide for practitioners and sets out fundamental principles for graduate students in civil, structural and mechanical engineering.

    Arnold C. Y. Yong is a senior civil engineer at Sepakat Setia Perunding (SSP) in Malaysia. He earned his PhD degree at the University of Melbourne where he continued his research as a post-doctoral fellow. During his time at the university, his research primarily focused on collision actions on structures. He led a number of experimental programs involving large-scale dynamic testing funded by the Australian Research Council (ARC), and has provided expert advice to the Geotechnical Engineering Office (GEO) of the Government of the Hong Kong Special Administrative Region to assist developing design guides for protection against landslides and rockfalls on hillslopes in built-up areas.

    Nelson T. K. Lam is a professor and leader of the Structures and Buildings Discipline in the Department of Infrastructure Engineering at the University of Melbourne. He is editor of the Australian Journal of Structural Engineering, member of the Structural College Board of Engineers Australia and a member of the committee responsible for the Australian standard for seismic actions. Nelson has earned many awards for his research, including the Chapman Medal (1999, 2010, 2019) and Warren Medal (2006) from Engineers Australia.

    Scott J. Menegon is a consulting structural engineer and academic with expertise in reinforced concrete, earthquake engineering and collisions actions. Scott earned his PhD from the Swinburne University of Technology, where he was the joint inaugural recipient of the prestigious Dr William Piper Brown AM scholarship. Scott currently works in industry and maintains his affiliation with Swinburne as an Adjunct Industry Fellow. His achievement in research was recently recognised by the award of the Chapman Medal (2019) by Engineers Australia.
