Dynamic Behavior of Rocking and Hybrid Cantilever walls in Precast Concrete Building

Abstract

This paper discusses the dynamic response of precast, post- tensioned, rocking, and hybrid cantilever walls that provided lateral force resistance to a three-story precast concrete building built at half-scale. The building was subjected to extensive shake- table testing on the NEES large high-performance outdoor shake table. The tests provided a landmark opportunity to observe the dynamic response of this type of lateral force-resisting system. Excellent performance was observed overall. Comparison between the assumptions made during the design of the wall and the exper- imental results allowed the validation of the presented design procedure and of the reinforcement detailing in the critical region at the base of the walls.
