- Abstract
- Limited wind speed measurements obtained during landfall of Hurricane Andrew in south Florida and wind speed estimates obtained from a computer-based model and from analyses are summarized and compared with code-specified design speeds for the affected area. Published reports of wind damage to manufactured homes and to conventional wood-framed dwellings are reviewed to identify modes of failure and intensity of damage. In general, manufactured homes which were built subsequent to issuance of the Manufactured Home Construction and Safety Standards (MHCSS) suffered less damage than did units built prior to issuance of the MHCSS. However, conventional residential construction performed better than did manufactured homes, including HUD-labeled units. Wind load provisions of selected codes and standards are compared and it is concluded that ASCE Standard 7-88 (Minimum Design Loads for Buildings and Other Structures) should be the basis for upgrading and improving the current wind load requirements of the MHCSS. Draft wind load requirements of the HUD Proposed Rule are reviewed and it is concluded that some clarification and refinement of these requirements are in order.
