Seismic Evaluation Of The Cumberland River Bridges On I-24 In Western Kentucky, Wael A. Zatar, Wei-Xin Ren, Issam E. Harik

Kentucky Transportation Center Research Report

The main objective of this study is to assess the structural integrity of the I-24 parallel bridges at the Cumberland River crossing in western Kentucky. Due to its importance, the bridge is evaluated for the 250-year event and the maximum credible 500-year event. The scope of the work included: 1) Field testing of the main bridge; 2) Finite element modeling and calibration; 3) Time-history seismic response analysis for the main spans; and 4) Seismic evaluation for both the main and the approach spans. The seismic analysis for the 250-year event indicates that the main spans of the bridge can resist …

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

Kentucky Transportation Center Research Report

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 …

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

Kentucky Transportation Center Research Report

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 …

Site Investigation Of Bridges Along I-24 In Western Kentucky, Wael Zatar, Issam E. Harik, Peng Yuan

Kentucky Transportation Center Research Report

Determination of the seismic risk of the I-24 bridges requires evaluating the current condition of all individual elements of the bridges. All bridges along the I-24 were visually inspected, pictured, and the records were stored in a database. Data of the visual inspection and the pictures were combined to form the completed site inspection forms of the I-24 bridges. Main visually observed deficiencies of the bridge elements were pointed out. The site inspection forms of all bridges on/over the I-24 in western Kentucky are used together with the bridge inventory to obtain different statistical figures regarding the characteristics of the …

Seismic Evaluation Of I-24 Bridges And Embankments In Western Kentucky–Summary Report, Wael A. Zatar, Issam E. Harik, Ching Chiaw Choo

Kentucky Transportation Center Research Report

I-24 is considered as one of the high priority and emergency routes in the region. Hence, it is essential that I-24 remains functional and operational after an earthquake event. The objective of this study is to perform seismic evaluation and risk assessment of bridges and embankments along I-24 in western Kentucky. The assessment assists identifying and prioritizing bridges that are susceptible to failure.

The study aims at evaluating the seismic risk for 127 bridges, of which 82 bridges lies on I-24 and 45 bridges cross over I-24. This report is the first (1st) in a series of seven reports for …

Coatings, Sealants, And Fillers To Address Bridge Concrete Deterioration And Aesthetics-Phase 1, Sudhir Palle, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

This study addresses experimental evaluation and testing of concrete coatings for maintenance purposes on structural (steel reinforced) concrete. The test methods employed are intended to identify coatings and sealers for eventual incorporation into a qualified products list for structural concrete coatings. Some of the methods/procedures used in this study will be used in the future to evaluate additional coatings and sealers. Developmental work focused on identifying relevant coatings systems and laboratory tests. The objectives of experimental project monitoring were to: 1) identify existing viable concrete coatings along with their properties/ characteristics/surface preparation requirements and determine effective acceptance/evaluation tests for those …
