摘要

In current structural engineering practice in California, there are significant variations in how the seismic analyses of light-framed wood multi-story residential buildings are performed. The most significant variations are in the analysis techniques, as well as in the areas of modeling diaphragm and shear wall rigidity. For background code information on this topic, refer to Mochizuki and Fennell, (2002).rnThis paper will provide a brief summary of the application of flexible and rigid diaphragm design assumptions, current design practices and code criteria, shear wall deformations, shear wall modeling techniques and a step by step three dimensional modeling procedure that incorporates non-linear shear wall behavior into a linear analysis. This procedure provides a reasonable distribution of shear forces to shear walls and facilitates the calculation of building drifts as required by code. The goal is to demonstrate that analysis of rigid diaphragm behavior, multi-story shear wall deformations, and building drift via three dimensional modeling is feasible and practical for this building type.rnAlthough this paper focuses on light-framed wood multistory buildings, many of the methodologies and conclusions are likely also appropriate for light-framed light gauge steel multi-story buildings.
