Cable Frequency Survey of the Hartman Bridge - 3/23-24/98.
Abstract
Whitlock, Dalrymple, Poston and Associates, Inc. (WDP) has been selected to
conduct a project to evaluate and repair cable-stay vibrations at the Fred
Hartman and Veterans Memorial Bridges. The primary purpose of the overall
project is to mitigate damage and risk for, and increase public confidence
in, the Fred Hartman and Veterans Memorial Bridges by preventing or reducing
stay-cable vibrations. The specific objectives of the overall project include
the following: 1) design/construction document review, 2) literature review,
3) aerodynamic analysis, 4) dynamic response analysis, 5) component analysis,
6) failure analysis, 7) wind tunnel testing (if required), 8) monitoring (Fred
Hartman and Veterans Memorial), 9) field evaluation (Fred Hartman and Veterans
Memorial), and 10) repair program (Fred Hartman and Veterans Memorial).
The primary purpose for the University of Kentucky (UK) to participate is to
provide structural dynamic model correlation and analysis to evaluate repair
alternatives for prevention and reduction of stay-cable vibrations for the
Fred Hartman and Veterans Memorial Bridges. UK efforts will contribute to
the overall project specific objectives: literature review, dynamic response
analysis, field evaluation, and monitoring. The twelve-month project is being
completed by Matt Johnson and Michael Schrader, Dept. of Civil Engineering, University of Kentucky under the direction of Dr. Suzanne Weaver Smith, P.E.
