Preliminary Seismic Evaluation And Ranking Of Bridges Along I-24 In Western Kentucky, Wael Zatar, Issam Harik, Peng Yuan, Ching Choo

Issam E. Harik

This study represents one of the Seismic Evaluation of I-24 Bridges investigative series. The focus is on preliminary seismic evaluation and ranking of bridges according to their seismic vulnerability. Bridges along I-24 are considered in this investigation. The ranking will assist in identifying and prioritizing bridges for secondary evaluation, retrofit measure, or other course of action. The rating system described herein is based on a methodology provided by the FHWA Retrofitting Manual for highway bridges. One hundred and twenty seven (127) highway bridges were evaluated and rated in this process for projected 50-year and 250-year seismic events. The Tennessee River …

Detailed Seismic Evaluation Of Bridges On And Over The Parkways In Western Kentucky, Jian Xie, Issam Harik, Tong Zhao

Issam E. Harik

This report outlines a rating system and details an evaluation procedure for the seismic evaluation of highway bridges. These processes are later used to investigate the structural integrity of selected highway bridges on and over the parkways in Western Kentucky. A total of 349 bridges were rated with the bridge ranking system, and 17 were selected for detailed seismic evaluation.

The capacity/demand ratio method developed by the Federal Highway Administration is employed for the detailed evaluation of bridges. The evaluation involves creating three-dimensional finite element models for all 17 bridges. Dynamic analysis is performed for a projected 250-year event. Among …

Ranking And Assessment Of Seismic Stability Of Highway Embankments In Kentucky (Kyspr 96-173), Kevin Sutterer, Issam Harik, David Allen, Ron Street

Issam E. Harik

This report presents the findings of three independent studies under the same grant. These were (a) assess and rank highway embankments along priority routes in western Kentucky according to seismic stability, (b) assess the seismic stability of the approach embankment for the U.S. 51 Ohio River crossing near Wickliffe, Kentucky, and (c) evaluate the seismic stability of the U.S. 41 Ohio River twin spans north of Henderson, Kentucky. Seismic stability of bridge foundations was not a part of this study. The highway ranking assessed over 400 embankments and delineated each as having high, moderate, or little risk of significant failure …

Preliminary Seismic Evaluation And Ranking Of Bridges On And Over The Parkways In Western Kentucky, Jian Xie, Issam Harik, Tong Zhao, Jindong Hu

Issam E. Harik

Five parkways in Western Kentucky are located in the region that is greatly influenced by the New Madrid and Wabash Valley Seismic Zones. This report executes a preliminary screening process, known also as the Seismic Rating System, for bridges on and over parkways in Western Kentucky to identify the seismic vulnerable bridges.

The ranking of bridges derived from this rating system is based on: structural vulnerability, seismic and geotechnical hazards, and bridge importance. There are 349 bridges were ranked with the Seismic Inventory of Bridges (SIB), a user-oriented database program developed according to the Seismic Retrofitting Manual. The bridge ranks …

Seismic Evaluation And Ranking Of Embankments For Bridges On And Over The Parkways In Western Kentucky, Han Shan Ding, Issam E. Harik, Ching Chiaw Choo

Issam E. Harik

This study represents one of the Seismic Evaluation of Bridges on and over the Parkways in Western Kentucky investigative series. The effort is focused on the seismic vulnerability of bridge embankments against slope instability and liquefaction potential. An evaluation and rating procedure is presented to assist in identifying and prioritizing bridge embankments that are susceptible to failure due to projected seismic events. To expedite the process, the algorithm titled Seismic Assessment System for Bridges (SASB) was programmed. Three hundred and eight-nine (389) bridge embankments (parallel bridges included) along the five western Kentucky parkways – Audubon, Pennyrile, Purchase, Western Kentucky, and …

Site Investigation Of Bridges On And Over The Parkways In Western Kentucky, Jindong Hu, Tong Zhao, Issam Harik, Jian Xie

Issam E. Harik

Determination of the seismic risk of the bridges on and over the parkways in Western Kentucky requires evaluating the current condition of the individual elements of the bridges. Except for culverts, all bridges were visually inspected, photographed and the records were stored in a database. Data of the visual inspection and the photographs were combined to form the completed site inspection forms. Any visually observed deficiencies of the bridge elements were recorded.

A Compact Disc (CD) that includes pictures of the bridges is attached to this report. The site inspection forms of all bridges on and over the parkways in …
