Abstract
Hurricane resistant design has focused on trying down roofs, and on tracing a load path through the frame. However, this emphasis on frame, and on imagined load paths is naive in the context of the wood frame house. Sheathing in structurally integral; even drywall. Response is non-linear, and even more, important; the structure is highly indeterminate. This work describes the complexity and contradiction in the structural responses of wood-frame houses. Focusing on the structural response of two simple house types - the hip roof and gable roof ranch houses - descriptions are provided for loading and reponse. A series of competing load paths are identified on the basis of non-linear diaphragm action, and on the effects of fasteners.
