Retrofit Of The Louisa-Fort Gay Bridge Using Cfrp Laminates, Ching Choo, Tong Zhao, Issam Harik

Issam E. Harik

This report details the processes pertaining to the repair and strengthening of the Louisa-Fort Gay Bridge, Lawrence County, KY, using advanced composite materials. Site inspections revealed flexural cracks in the reinforced concrete girders of the continuous bridge structure. To determine the cause of these cracks, an evaluation was initiated based on vehicle classification and truck weight data. The results confirmed that certain reinforced concrete girders were stressed beyond the limits allowed by the AASHTO Code. A retrofit scheme using carbon fiber reinforced polymer (CFRP) composite was devised and the amount of CFRP laminates needed for flexural strengthening was determined from …

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

Issam E. Harik

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.

For …

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 …

Experimental Analysis And Analytical Modeling Of Bridges With And Without Diaphragms, James J. Griffin, Issam E. Harik, David L. Allen

Issam E. Harik

Two prestressed concrete (P/C) I-girder bridges along the coal haul route system of Southeastern Kentucky were constructed with a 50 degree skew angle. One of the bridges has concrete intermediate diaphragms, while the other bridge has no intermediate diaphragms. Bridges of similar design along coal haul routes have experienced unusual concrete spalling at the interface of the diaphragms and the bottom flange of the girders. The purpose of this report is to identify the cause of the damage, and to evaluate the effectiveness of intermediate diaphragms.

Dynamic Site Periods For The Jackson Purchase Region Of Western Kentucky, Ron Street, Zhenming Wang, Edward Woolery, Issam Harik, David Allen, Kevin Sutterer

Issam E. Harik

Bridges, overpasses, and other engineered structures in the Jackson Purchase region of Western Kentucky are, of necessity, built on a thick column of loose to semi-consolidated sediments. Because these sediments tend to amplify seismically induced ground motions at preferred periods, structures with natural periods close to the preferred periods of amplification of the ground motions are particularly vulnerable to damages during an earthquake because of in-phase resonance.

For this report, conventional seismic refraction and reflection techniques were used to determine the shearwave velocities of the more poorly consolidated, near-surface sediments for a matrix of sites in the region. Conventional seismic …

Structural Evaluation Of The John A. Roebling Suspension Bridge – Element Level Analysis, Ching Choo, Issam Harik

Issam E. Harik

The primary objective of the structural evaluation of the John A. Roebling Bridge is to determine the maximum allowable gross vehicle weight (GVW) that can be carried by the bridge deck structural elements such as the open steel grid deck, channels, standard sections, or built-up sections. To achieve this objective, an “Element Level Analysis” is carried out. The maximum allowable GVW for different truck and bus types are presented for different levels of structural elements sectional loss.

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 …

Performance Evaluation Of Bridges With Structural Bridge Deck Overlays (Sbdo), James Griffin, Issam Harik, Ching Choo

Issam E. Harik

Structural Bridge Deck Overlay (SBDO) involves applying 6 to 10 inches (150 to 200 mm) of normal weight, class AA, reinforced concrete directly to a bridge’s original slab. The overlay is designed to increase the deck elevation to an extent that standard highway resurfacing procedures can continue uninterrupted up the edges of the bridge. Otherwise, excavation along the bridge approaches or jacking of the superstructure is required to insure proper elevation. Experimental static field tests were conducted on three different bridges: (1) Simply supported prestressed concrete I-girder bridge; (2) cast-in-place reinforced concrete continuous haunched girder bridge; and (3) cast-in-place reinforced …

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 …
