Stability and Strength Behavior of Thin-Walled Roof-Panel-Purlin System under Wind Loading
Integrated computational fluid dynamics and finite element based studies examining the stability and strength behavior of thin-walled structures’ cladding and component systems subjected to realistic wind loading are conducted. Spatial variation of wind and wind-directionality impact on the buckling and collapse modes of the light-weight steel roof panel-purlin system underscore the need for proper accounting of spatiotemporal wind effects on low-rise buildings in improving current limitations in wind analysis and design, and highlighting future potential extreme wind-hazard mitigation implementation with structural-aerodynamic optimization of thin-walled structures.
