Abstract: The research focused on the behavior of two manufactured 14 × 66 ft houses under simulated wind loads. Extensive instrumentation was employed to insure the collection of data that would enable evaluation of the influence of interior wall arrangements on whole-house behavior. Both concentrated and uniform lateral loads were applied to the test structures. The concentrated loads were applied at transverse (shear) wall locations, one load at a time, to enable evaluation of the in-place stiffness of the loaded wall in relation to the other walls. Subsequent to the full-scale testing, racking tests were performed on individual walls constructed following the same plans and specifications used for the walls in the full-scale tests. The load-deflection data were used in conjunction with the full-scale test results to assess the distribution of lateral load to transverse walls. The results of the tests and the analysis of the system behavior are reported. The implications of the results for current and future design procedures are discussed.
