Indiana Local Road And Bridge Conditions, Indiana Ltap

Indiana Local Technical Assistance Program (LTAP) Publications

In response to an appilcation requirement for the Community Matching Grant Fund Program, 354 asset management plans for roads and bridges were submitted in 2016 which contain the current conditions of local agency roads and bridges. This report describes these conditions and suggests the funding levels necessary to improve and maintain these assets at defined condition levels over a ten-year period. A ten-year horizon was used so as to correspond to previous LTAP studies performed in 2003 and 2009. The ten-year time period is also comparable to other Indiana studies.

Aesthetic Coatings For Concrete Bridge Components, Brent Kriha

Theses and Dissertations

This thesis evaluated the durability and aesthetic performance of coating systems for utilization in concrete bridge applications. The principle objectives of this thesis were: 1) Identify aesthetic coating systems appropriate for concrete bridge applications; 2) Evaluate the performance of the selected systems through a laboratory testing regimen; 3) Develop guidelines for coating selection, surface preparation, and application.

A series of site visits to various bridges throughout the State of Wisconsin provided insight into the performance of common coating systems and allowed problematic structural details to be identified. To aid in the selection of appropriate coating systems, questionnaires were distributed to …

Evaluation Of Redundancy Of Twin Steel Box-Girder Bridges, Huy V. Pham

FIU Electronic Theses and Dissertations

Based on the definition given in the AASHTO LRFD Bridge Design Specifications, twin steel box-girder bridges are classified as bridges with fracture critical members (FCMs), in which a failure of a tension member is expected to lead to a collapse of the bridge. However, a number of such bridges with either a partial or full-depth crack in one girder have been reported and are still providing service without collapsing. The main objective of this research project is to understand the behavior of twin steel box-girder bridges and to develop methods for evaluating their redundancy level in the event of the …

Development Of A Transition Between An Energy-Absorbing Concrete Barrier And A Rigid Concrete Butress, Tyler L. Schmidt, Ronald K. Faller, Jennifer D. Schmidt, John D. Reid, Robert W. Bielenberg, Scott Rosenbaugh

Nebraska Department of Transportation: Research Reports

From 2010 to 2015, MwRSF researchers developed the RESTORE barrier, which is a restorable MASH TL-4 median barrier with a steel and concrete rail supported by elastomer posts and steel skids. The research effort reported herein describes the initial development of a transition from the RESTORE barrier to a rigid TL-4 concrete buttress.

The previously-developed RESTORE barrier LS-DYNA model was validated against three full-scale vehicle crash tests. Several design concepts were generated through a series of brainstorming efforts. The primary transition concept consisted of a pin and loop connection between the RESTORE barrier and rigid concrete buttress, which was designed …

Bridge Deck Research At The University Of Tennessee: A Summary Thesis, Lindsey Brooke Phelps

Masters Theses

Currently, there has been no compilation of all the research the University of Tennessee has completed on chloride ion penetration in concrete bridge decks. The following thesis is a brief summary of the work that has been completed under Dr. Edwin Burdette’s direction over the last six years along with some additional literature review. The testing consisted of Surface Resistivity and Rapid Chloride Ion Penetration testing. This testing showed that there is, in fact a correlation between the two test methods, though SR testing is much easier to conduct. Considerable testing was completed on bridge decks throughout the state of …

Seismic Design Of A Prestressed Concrete Bridge, Alperen Ozel

University of New Orleans Theses and Dissertations

Latest advancements in software have become an indispensable tool in structural analysis. The main goal of this thesis is to examine dynamic responses of bridges in seismic activity with the help of such tool as CSi Bridge. Therefore, throughout this study, a prestressed concrete bridge model will be thoroughly designed. In the first section, the required materials and structural components will be introduced. The following section will cover calculations required for modeling. The actual modeling of the structure will be carried out in Section 3. In Section 4, the set of required analysis for seismic design such as modal, pushover …

Live-Load Test And Finite-Element Model Analysis Of A Steel Girder Bridge, Jake L. Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah Transportation Center in conjunction with the Mountain Plains Consortium sponsored a study to investigate the performance, and condition of a steel, twin, I-girder bridge. The bridge is located on the Idaho-Oregon border near Payette, Idaho, and was designed to carry traffic over the Snake River.

Bridge Diagnostics Inc. was contracted by the Idaho Transportation Department to perform a live-load test on the bridge. This testing included the placement of 62 gauges that measured the response of the bridge as heavy trucks were driven across it.

A 3-D finite-element model of the bridge was generated and compared to the …

Warning Systems Evaluation For Overhead Clearance Detection, Clayton Rogers

GS4 Georgia Southern Student Scholars Symposium

The accurate detection of road vehicle heights is a need that arises in departments of transportation across the nation. Usually, this dimension is required to solve various transportation issues. In particular, numerous bridges in the state of Georgia have been affected by repetitive crashes of tall vehicles against their structural elements. As an example, a recent inspection report of the Houlihan Bridge over the Savannah River documents damages resulting from numerous hits by overheight vehicles. This case emphasizes the urgency of finding preventive measures. To address this issue, a number of solutions are investigated. The known methods of vehicle height …

Integrated Solar Technologies With Outdoor Pedestrian Bridge Superstructure Decking, Richard K. Racz

Masters Theses

Solar technology has been a major topic in sustainable design for many years. In the last five years, however, the solar technology industry has seen a rapid growth in installations and technological advances in cell design. Combined with a rapidly declining overall system cost, the idea of introducing solar technology into a wider range of applications is becoming a focus for engineers and scientists around the world. So many variables which alter solar energy production, such as the sun and surrounding environment, determine whether a solar design is beneficial. This thesis presents a bridge deck surface integrated with solar cells …

Static And Dynamic Characterization Of Tied Arch Bridges, John Edward Finke

Doctoral Dissertations

"Tied arch bridges have been designed and constructed since the late 19th century. With their open vista owing to minimalist features tied arch bridges continue to appeal the public. Tied arch bridges are both aesthetic and economical alternates to long span bridges holding a place in the hierarchy of major bridges. They fit in a niche between viable and economical plate girder spans and short cable stayed bridge spans. There are several variations of the tied arch with the most common form being those having vertical hangers, stiff tie girders and slender arch ribs. This tied arch variation is examined …

Use Of Sacrificial Embankments To Minimize Bridge Damage From Scour During Extreme Flow Events, Matthew Willi Brand

Graduate College Dissertations and Theses

The leading cause of bridge failure has often been identified as bridge scour, which is generally defined as the erosion or removal of streambed and/or bank material around bridge foundations due to flowing water. These scour critical bridges are particularly vulnerable during extreme flood events, and pose a major risk to human life, transportation infrastructure, and economic sustainability. Climate change is increasing the intensity and persistence of large flow events throughout the world, further straining bridge infrastructure. Retrofitting the thousands of undersized and scour critical bridges to more rigorous standards is prohibitively expensive, and current countermeasures inadequately address the core …
