Performance Analysis of Engineered Bamboo Composites for Resilient Anti-Hailstorm Structures under Multihazard Loading

The increasing frequency and intensity of hailstorms due to climate variability have highlighted the need for resilient, cost-effective, and sustainable protective structures. This study investigates the structural performance and environmental advantages of bamboo-based composite frameworks designed to withstand hail, wind, and rainfall loads. The research focuses on Dendrocalamus strictus (Manvel bamboo), a species abundantly available in India, assessing its mechanical response and stability compared to conventional steel and hybrid bamboo-steel structures. Using STAAD.Pro V8i software, three structural configurations—pure steel, pure bamboo, and bamboo-steel composites—were analyzed under simulated conditions of 134 km/h wind speed, 0.36 kN/m hail load, and 0.39 kN/m rainfall load. The results demonstrate that bamboo exhibits strong tensile performance and superior flexibility, effectively absorbing and redistributing dynamic loads. However, under extreme conditions, hybrid bamboo-steel systems showed reduced deflection and higher load-bearing capacity, achieving optimal stability. The findings confirm bamboo’s viability as a sustainable material for protective frameworks in moderate hailstorm-prone regions, while hybrid designs are recommended for more severe climates. This research supports the integration of renewable materials into resilient design practices, contributing to sustainable infrastructure development and reduced environmental impact.
