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 …

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 Bridge Embankments Along I-24 In Western Kentucky, Wael Zatar, Issam E. Harik, Peng Yuan, Ching Chiaw Choo

Issam E. Harik

This study represents one of the Seismic Evaluation of I-24 Bridges investigative series. The focus is on slope or embankment stability and liquefaction potential of embankments of bridges along I-24 in Western Kentucky. A rating system is derived to assist in identifying and prioritizing bridge embankments that are susceptible to failure during to projected seismic events. Embankments of one hundred and twenty seven (127) bridges along I-24 in Western Kentucky are evaluated for 50-year and 250-year seismic events. Fifty-two (52) of the 127 embankments were rated as ‘critical’ for the 50-year event, and 60 were rated as ‘critical’ for the …
