Seismic Design and Behavior of Steel Frames with Controlled Rocking—Part I: Concepts and Quasi-Static Subassembly Testing
Research and experience of past earthquakes suggest the need for buildings that are less vulnerable to damage and easier to repair after a major earthquake. Our research aims to develop a new structural system that employs controlled frame rocking action and replaceable structural fuses to provide safe and cost effective resistance to earthquakes. The system combines desirable aspects of conventional steel-braced frame systems with energy dissipating shear fuses that are mobilized through rocking action. Vertical post-tensioning is provided to increase overturning resistance and enhance the self-centering characteristics to reduce residual drifts. This is the first of two companion papers to present research findings from a NSF-NEES Small Group Project on this topic. This paper examines the behavior of controlled rocking systems through large (1/2) scale rocking-frame subassembly tests conducted at the University of Illinois. Conducted using quasi-static cyclic and hybrid simulation techniques, the tests demonstrate the viability of the controlled rocking system and provide the basis for establishing design criteria to ensure an appropriate balance of overturning resistance, self-centering capacity, and energy dissipation.
