Mobile Home Research. Transportation and Site-Installation. Transportation Test Program and Evaluation/Analyses of Test Data. Volume 2: 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 describes a test program conducted to obtain data that could be compared to analytically derived data, with emphasis placed on measured test data which resulted in equation modifications as necessary to best fit experimental data. Test data were obtained from singlewide and doublewide homes built per the current standard and from homes built prior to implementation of the current standard. Test homes were subjected to transportation and site installation conditions to simulate years of actual use. Research included a comparison of the effects of transportation on gypsum board interior mobile homes to plywood interior units for structural durability performance. Dynamic and stationary testing were used, as well as finite element modeling and dynamic analysis. This analysis involved evaluation of the mobile home while it was under tow for measurements of the apparent torsional and bending stiffness, examination of the stresses in elements and displacements of points, and estimation of the remaining useful life of the unit at the various stages in the testing. Tables, diagrams, and photographs are included. This is the second volume of a 7 - volume series. (Author abstract modified).
