Damage-Free Seismic-Resistant Self-Centering Concentrically-Braced Frames
Experiment Report. Self-centering steel concentrically braced frames (SC-CBFs) are being studied as part of an ongoing research program on self-centering seismic-resistant structural systems. This research was conducted at Lehigh University in collaboration with Princeton University and Purdue University under the NSF-funded NEESR program. The current research on SC-CBFs includes analytical parametric studies of a prototype structure designed for a site in Los Angeles, and the development of a reliability-based, performance-based design procedure for SC-CBFs. The research also features experimental testing of a 0.6-scale, four story SC-CBF at the NSF NEES RTMD Earthquake Simulation Facility at the ATLSS Engineering Research Center at Lehigh University in Bethlehem, PA. This report focuses on the performance-based design, experimental setup, material testing and stiffness testing of the 0.6-scale SC-CBF test structure.
