Long span roofs over large structures, such as stadiums and aircraft hangars, as well as enclosed or open-air fabric structures, are vulnerable to wind loading due to their light weight and aerodynamic shape. The damaging effects of wind on these structures can be investigated and mitigated as necessary through a series of wind tunnel tests. These tests involve the simultaneous use of pressure measurements on static models and direct force measurements on dynamic models.

At Gradient Wind, we have the necessary tools and practical experience to assist with the design development of complex roof structures. We help structural engineers and architects create efficient, safe and beautiful structures.

Snow loading and sliding are also important considerations for roof design. Using techniques as described by the Snow Drifting and Accumulation section, we can predict snow loads for any roof shape and its impact on surrounding buildings. We can also recommend mitigation strategies where required.
