To obtain a copy of a specific publication, users should contact the publication's publisher directly.

Abstract
Limited wind speed measurements obtained during landall of Hurricane Andrew in south Florida and wind speeds estimates obtained from a computer-based model and from analyses are summarized and compared with code specified design speeds for the affected areas. Published reports of wind damage to manufactured homes and to conventional wood framed dwellings are reviewed to identify modes of failure and intesity of damage. In general, manufactured homes which were built subsequent to issuance of Manufacuted Home Construction & Safety standards suffered less damage than did units built prior to issuance of MHCSS. Wind load provisions of selected codes & standards are compared & it is concluded that ASCE standard 7-88 should be the basis for upgrading and improving the current wind load required of the MHCSS. Draft wind load requirements of the HUD Proposed Rule are reviewed and itis concluded that some clarification and refinement of these requirements are in order.
