Seismic Performance Evaluation of the Bill Emerson Cable-Stayed Bridge with Measured Acceleration Records
Abstract
A 3D finite element model of the Bill Emerson Cable-stayed Bridge was developed and calibrated with the measured acceleration records taken during the May 1, 2005, earthquake. Under the design earthquake scaled up from the measured rock motions at the bridge site, all cables behave elastically with a safety factor of over 2.35. The two towers behave elastically in-plane. The upper towers above cap beams also remain elastic out-of-plane, but the lower towers approach yielding.
