This creates a net pressure effect that is fundamentally different from how an enclosed building&#8217;s facade experiences pressure on a single exposed surface.<\/span><\/p>\n<h2><b>Where the Single-Surface Simplification Enters<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Engineers accustomed to enclosed building wind load calculations, where a single exterior surface pressure is the primary consideration, may apply a similar single-surface logic to an open structure like a canopy \u2014 evaluating pressure only on the upper surface, for instance, without accounting for the simultaneous pressure acting on the underside.<\/span><\/p>\n<h2><b>Why This Understates the Real Loading Condition<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The net pressure on an open structure reflects the combined effect of pressure on both surfaces acting together, which can produce a higher net force than either surface&#8217;s individual pressure would suggest in isolation. A calculation that only evaluates one surface is not simply incomplete \u2014 it is calculating a fundamentally different, and lower, loading condition than what the open structure will actually experience.<\/span><\/p>\n<h2><b>Applying Correct Open-Structure Methodology<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">After explaining how open structures require net pressure calculation across both surfaces, the fix is applying the specific open-structure provisions the code provides for this category, rather than adapting enclosed-building logic to a structure type it was never designed for. Wind Master applies the correct open-structure methodology to canopies and similar elements, calculating net pressure across both exposed surfaces rather than defaulting to single-surface enclosed-building assumptions.<\/span><\/p>\n<p><b>Validate your open-structure calculations \u2014 Audit your net pressure methodology.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculating canopy and open structure wind loads using single-surface pressure assumptions misses the net pressure effect created by wind acting on both exposed surfaces simultaneously \u2014 a simplification that understates the real loading condition these structures experience.
