Mobile Home Research. Transportation and Site-Installation. Recommended Revisions to Federal Mobile Home Construction and Safety Standard Resulting from the Transportation Study. Volume 5: Final Report

摘要

This report provides a basis for determining the adequacy of the Mobile Home Construction and Safety Standards, effective June 15, 1976. The Southwest Research Institute's study offers an innovative approach to assess mobile home structural durability or degradation, and its findings should offer a base upon which to develop proposed standards. This volume contains proposed changes to the current standard based on an analysis of data contained in volumes 1 through 4 of this report. The objective of these revisions is to reduce the degradation of mobile homes where current practices result in predicted and observed degradation that exceeds acceptable levels. The proposed changes include increased design loads to resist in - transit and on - site forces, increased design criteria for attachment of joints as required to minimize loosening of joints during transportation, and a requirement for a minimum integrated structure stiffness criteria to ensure that degradation with respect to time is consistent with a reasonable useful life. Recommended design loads were based on actual measured test data multiplied by a factor selected to account for a rough roads and highway speeds greater than 45 miles per hour. Minimum stiffness criteria were based on values obtained from the singlewide home built to the current standards. Tables and graphs are included. This is the fifth volume of a 7 - volume series.
