Seismic Evaluation Of The Ohio River Bridge On Us51 At Wickliffe, Kentucky, Issam E. Harik, Chelliah Madasamy, Denglin Chen, Leonong Zhou, Kevin Sutterer, Ron Street, David L. Allen

Issam E. Harik

This report presents the of seismic evaluation of the Ohio river bridge on US51 at Wickliffe, Kentucky. The main bridge is a five-span single-deck cantilever through-truss type. The approach bridge has 21 spans on the Kentucky side and 6 spans on the Illinois side. Although this bridge has not yet been subjected to a moderate or major earthquake, it is situated within the influence of the New Madrid seismic zone. The seismic evaluation program consists of field testing and seismic response analysis. The modal properties of the main bridge are determined through field testing, and are used to calibrate the …

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

Issam E. Harik

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 …

Source Zones, Recurrence Rates, And Time Histories For Earthquakes Affecting Kentucky, Ron Street, Zhernning Wang, Issam E. Harik, David L. Allen, James J. Griffin

Issam E. Harik

Time histories of hypothetical earthquakes, along with their peak-particle accelerations, and 0 and 5 percent damped response spectra are developed as guidelines for the seismic design of highway structures and bridges within Kentucky. The time histories are derived through the use of random vibration analyses, and take into consideration the probability of earthquakes from nearby seismic zones, the attenuation of ground motions with distance in the Central United States, and the possibility of a random event occurring outside of the generally recognized zones of seismicity in the area. Suggested peak-particle accelerations, time histories, and response spectra are intended for use …

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

Issam E. Harik

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 …

Seismic Evaluation Of The Us41 Northbound Bridge Over The Ohio River At Henderson, Ky, Issam E. Harik, Chelliah Madasamy, Denglin Chen, K. Vasudevan, Leonong Zhou, Kevin Sutterer, Ron Street, David L. Allen

Issam E. Harik

This report presents the seismic evaluation of the US41 Northbound bridge over the Ohio River connecting Evansville, Indiana and Henderson, Kentucky. The main bridge is a four-span cantilever through-truss type. The approach bridge has 8 spans on the Evansville, IN side and 35 spans on the Henderson, KY side. Although this bridge has not yet been subjected to a moderate or major earthquake, it is situated within the influence of the New Madrid and Wabash Valley Seismic Zones.

The seismic evaluation program consisted of field testing and seismic response analysis. The modal properties of the main bridge were determined through …

Seismic Evaluation Of The Us41 Southbound Bridge Over The Ohio River At Henderson, Ky, Issam Harik, K. Vasudevan, Chelliah Madasamy, Denglin Chen, Leonong Zhou, Kevin Sutterer, Ron Street, David Allen

Issam E. Harik

This report presents the seismic evaluation of the US41 Southbound bridge over the Ohio River connecting Evansville, Indiana and Henderson, Kentucky. The main bridge is a four-span cantilever through-truss type. The approach bridge has 9 spans on the Evansville, IN side and 20 spans on the Henderson, side. Although this bridge has not yet been subjected to a moderate or major earthquake, it is situated within the influence of the New Madrid and Wabash Valley Seismic Zones. The seismic evaluation program consisted of field testing and seismic response analysis. The modal properties of the main bridge were determined through field …
