Abstract
  • The objectives of this study are to use SAP2000 to investigate lateral load paths and system behavior in a modular, light-frame wood structure by investigating different foundation configurations and to further develop and validate existing modeling techniques of shear wall elements based on the Perforated Shear Wall Method. The modeling methods were validated using full-scale tests on sub-assemblies and rectangular and L-shaped houses by previous researchers. ASCE 7-10 main lateral-force-resisting system and components and cladding wind loads are applied in perpendicular directions to the exterior walls. The analysis is performed for a series of foundation types to examine the effects on overall and local behavior. The effectiveness of the different foundation schemes was evaluated. It was found that the racking shear stiffness calibration procedures implemented previously for light-framed construction are also applicable for light-frame, modular shear walls. Additionally, it was found that anchorage elongation substantially affects the racking shear stiffness of shear walls with aspect ratios within limits similar to those provided by the Special Design Provisions for Wind and Seismic Design Standards. For regularly-shaped modular structures, it was found that assuming tributary areas to resisting elements for lateral loads produced conservative demands when ignoring contributions from uplift pressures. Thousands of structures such as these are used throughout the United States in various applications. Consequently, with wind loads being a major contributor to annual structural damage of light-framed wood structures and a need for methods to sufficiently evaluate load paths, this study is an important development in the design of modular buildings and their acceptance by building code officials.
