Abstract
Widespread damage to manufactured homes associated with Hurricane Andrew and other more recent catastrophic events points toward the need for research addressing their structural performance when subjected to high winds. To improve the level of engineering for manufactured housing, the U.S. Department of Housing and Urban Development (HUD) is developing a Desktop Design Tool under the administration of the Idaho National Engineering and Environmental Laboratory (INEEL). The state-of the-art for lateral load analysis of manufactured homes is not sufficiently accurate to allow current rational design for these complex three-dimensional structural systems. Thus, to predict the behavior of a manufactured home subjected to wind loading, a threedimensional analysis of the complete structure is required. The purpose for the Desktop Design Tool is to provide a three-dimensional, system-based analysis capability for designers of manufactured homes. The focus of this research was to develop analysis techniques that can be used to accurately model the behavior of shear walls within manufactured homes. The method presented is an improvement over existing methods because it can be applied without first doing detailed wall testing. Then, a structural analysis module was developed and verified for use within the Desktop Design Tool to evaluate the performance of manufactured homes when subjected to wind load. The module includes an interface element, which was developed to enable the determination of one of the major results desired from the analysis module, which is the force at connections between walls and diaphragms and across the mating line. The results, in comparison with full-scale tests, are promising in that the model correctly predicts the overall behavior of the structure.
