Integrated Aerodynamic–Structural Validation Framework for Wind-Induced Load Assessment

Applied Sciences
Understanding wind–structure interaction (WSI) in low-rise buildings remains a significant challenge in wind and structural engineering, particularly under highly turbulent and non-stationary wind phenomena such as downbursts and tornado-like vortices ...
