Abstract

Although elastic design of the main wind force resisting system in a building is the conventional approach it is not always desirable. In this study, nonlinear static and dynamic analyses are used to predict the inelastic behavior of a three-story building with concrete-filled composite plate shear walls subjected to wind loads. To explore the potential for inelastic design, two types of planar composite shear wall buildings are examined: individual shear walls designed using an elastic approach, and coupled shear wall pairs designed using an inelastic approach adopted from seismic design provisions. Nonlinear static "pushover" analyses are run using an assumed wind load profile to determine the static system overstrength. Incremental nonlinear dynamic response history analyses are run using wind loads derived from wind tunnel test data to determine the wind collapse safety. The results from the static analyses show that the coupled shear walls have significant static system overstrength compared to the individual shear walls. The results from the dynamic analyses show that the coupled shear walls also provide superior structural safety. Taken together, the results indicate that inelastic wind design is feasible for the three-story building examined in this study and imply that inelastic wind design may be a viable design approach.
