Design and Validation of Steel Self-Centering Concentrically-Braced Frames
Abstract eng: Steel self-centering concentrically-braced frames (SC-CBFs), also known as rocking braced frames, are a relatively new seismic lateral force resisting system. Exceptional seismic performance of SC-CBFs has been demonstrated in a number of laboratory tests. There is not, however, a well-established design procedure for SC-CBFs available for practicing design engineers who wish to incorporate SC-CBFs into their structures. This paper presents a design procedure for SC-CBFs based on conventional response-spectrum analysis, modified to account for significant higher mode effects. This design procedure for SC-CBFs predicts story shears and overturning moments under the median design basis earthquake so that peak member force demands are determined that have a small probability of exceedance. Results of extensive analytical studies on SC-CBFs ranging in height from 4 to 12 stories designed with this procedure are presented to validate the SCCBF design procedure.
