Wind Design Problems with Building Structures During Construction

Abstract

A great deal of damage and loss of property are caused by wind during construction. Partially‐completed structures and temporary works that provide support, access, or protection present the greatest risks. The damaging winds are usually much lower than the design wind loads for completed structures. The design wind speed for short‐term exposure, the drag and shielding coefficients for partially completed structures, and the required temporary strength and stability need to be examined. U.S. building codes and standards provide inadequate or no guidance at all. There is a need to investigate, define, and mitigate the wind‐created risks on construction projects.
