Towards a Multi-Hazard Framework for the Design of Taller Timber Structures

Multi-hazard events, though infrequent and rare, are responsible for a substantial portion of global economic losses. This book chapter investigates the complexities of multi-hazard events and explores the design challenges and methodologies in multi-hazard risk assessment and structural resilience for wooden structures. Special attention is given to the interaction between earthquakes, fires, and blast loads on timber structures, highlighting the state of the art, the gaps in current research, and the potential for probabilistic design and analysis approaches to enhance understanding and improve structural resilience and robustness. The limitations of existing design codes and standards are reviewed and frameworks for assessing cumulative damage and risk under multi-hazard scenarios are discussed. The book chapter aims to provide the state of the art on the topic and guide future research and practical applications in designing timber structures capable of enduring multiple hazards, thereby enhancing the safety and sustainability of the built environment.
