Session Overview: The resilience of tensioned membrane structures is integral to their continued use as lightweight, efficient alternatives in building structures and critical infrastructure. While these structures are adaptive to dynamic forces, their performance in extreme conditions is more intricate when compared to more conventional materials such as steel and concrete. Challenges such as severe weather, environmental stresses, and other extreme factors introduce uncertainty in their design and expected service life. This technical session aims to enhance the collective understanding of the behavior of tensioned membrane structures under extreme conditions through case studies, research advancements, and lessons learned from past failures. The session will also explore improved design practices, predictive modeling techniques, and innovations in materials. Learning Objectives: Attendees will gain a deeper understanding of one or more of the following: (1) Practical insights and lessons learned from real-world case studies. (2) Advanced design strategies to enhance the resilience and performance of membrane structures in demanding environments. (3) The behavior of tensioned membrane structures under extreme environmental conditions, including high winds, heavy snow loads, other environmental stresses, and unusual conditions. (4) Emerging technologies and materials that improve durability, safety, and long-term performance of membrane systems.
