Seismic-Hazard Maps And Time Histories For The Commonwealth Of Kentucky, Zhenming Wang, Issam E. Harik, Edward W. Woolery, Baoping Shi, Abheetha Peiris

Kentucky Transportation Center Research Report

The ground-motion hazard maps and time histories for three earthquake scenarios, expected earthquakes, probable earthquakes, and maximum credible earthquakes on the free surface in hard rock (shear-wave velocity >1,500 m/s), were derived using the deterministic seismic hazard analysis. The results are based on (1) historical observations, (2) instrumental records, and (3) current understanding of the earthquake source, recurrence, and ground-motion attenuation relationship in the central United States. It is well understood that there are uncertainties in the ground motion hazard maps because of the uncertainties inherent in parameters such as earthquake location, magnitude, and frequency used in the study. This …

Seismic Isolation Of A Highly Skewed, Prestressed Concrete Girder Bridge, Bradley Neil Robson, Issam E. Harik, David L. Allen

Kentucky Transportation Center Research Report

A relatively new approach for designing or retrofitting highway bridges in seismic zones involves isolating the superstructure from the substructure. Through experimental and analytical investigations, this study evaluates the effectiveness of isolating one particular bridge: a highly skewed, prestressed concrete, slab-on-girder bridge. Dynamic testing of the bridge was performed using the pullback, quick-release method. A three dimensional finite element model of the bridge was created. It was refined, or calibrated, to match experimentally determined natural frequencies and mode shapes. Time-history analyzes, using site-specific acceleration records, were conducted for the seismically isolated bridge model and an identical, non-isolated bridge model.

Seismic Analysis Of The Brent-Spence Bridge, Issam E. Harik, David L. Allen, Ronald L. Street, Meiwan Guo, R. Clark Graves, Jack A. Harison, Mark J. Gawry

Kentucky Transportation Center Research Report

This report presents the findings of a seismic evaluation of the Brent-Spence bridge. The bridge is a double-deck cantilever through truss which was constructed in 1961; it is a critical highway link conveying 1-75 over the Ohio river. While not yet subjected to a moderate or major earthquake, the bridge is within the influence of the New Madrid, Wabash Valley, and Anna seismic zones.

The seismic evaluation program consisted of field testing and seismic analysis. The vibrational properties of the main bridge were determined through field testing and used to calibrate a 3-D finite element model. The model was then …

Plan For Continuing Earthquake Mitigation And Recommended Emergency Response Procedures For Western Kentucky, L. John Fleckenstein, David L. Allen, Vince P. Drnevich

Kentucky Transportation Center Research Report

Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. In 1987, the Kentucky Transportation Cabinet commissioned the Kentucky Transportation Center to analyze and assess the possible effects of an earthquake on highway facilities. Since 1987, over 1,000 miles of priority routes have been recommended for the transportation of goods and services after a major earthquake. This report summarizes the mitigation research that has been conducted. This report also discusses a plan for continuing earthquake mitigation in Kentucky through seminars, discusses bridge retrofitting, and makes recommendations for a post earthquake response.

Seismic Analysis And Retrofitting Priorities For Highway Bridges On Earthquake Priority Route System In Western Kentucky, Yu Ouyang, David L. Allen, Vincent P. Drnevich, L. John Fleckenstein

Kentucky Transportation Center Research Report

Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. Bridges, as the vital links of the priority route system, need to be prevented from sever earthquake damages in order to keep the routes passible after an earthquake has occurred. In this report, seismic rating and seismic analysis were performed for each of 276 bridges on the priority route system. A priority order of retrofitting for the bridges was listed according to their vulnerability to the earthquake. At least 111 bridges need retrofitting based on the results of seismic analyses. The …
