Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...
Resource Type:: Dissertation
Full Text:: States are substandard or deficient. Many deficient bridges are posted or closed to traffic, and repair

Effect of constituent materials and curing methods on the abrasion resistance and durability of high performance concrete for pre-cast pre-stressed bridge deck slabs

Creator:: Keshari, Shweta
Abstract:: This thesis is the consequence of a research effort undertaken by the School of Civil and Construction Engineering at Oregon State University and funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration (FHWA). The principal objective of the effort was to reduce the life cycle cost...

Shear repair methods for conventionally reinforced concrete girders and deep beams

Creator:: Howell, Daniel A.
Abstract:: Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...

Contemporary forest road management with economic and environmental objectives

Creator:: Thompson, Matthew P.
Abstract:: One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...

Highway finance and the impacts on road quality

Creator:: Knutson, Rachel L.
Abstract:: In recent years there has been concern over the deterioration and lack of adequate funding for the US road and highway system. The main goals of this study are to examine how increasing use of general financing methods effects road quality, to determine if capital outlay and maintenance expenditure impact...

The review of PPP toll roads in the US and the simulation of the Chicago Skyway

Creator:: Xu, Wei
Abstract:: As the traffic demand increases at a faster rate than the upgrade and maintenance of transportation facilities through the traditional public financing methods in the United States, the Public-Private Partnership (PPP) is becoming an important supplement to the public transportation infrastructure investment. There are already several existing PPP toll road...

Autotronics : Implications for automotive related training programs standards based upon emerging technologies

Creator:: Savin, Stuart
Abstract:: The purpose of the study was to provide a method for evaluating the effect, impact or role that (as perceived by automotive, diesel, automotive collision faculty and administrators) the nationally recognized industry training standards developed by Automotive Service Excellence (ASE) and National Automotive Technicians Education Foundation (NATEF) have on the...

Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...
Resource Type:: Masters Thesis
Full Text:: repair methods exist that can seal diagonal cracks and possibly restore or increase capacity, such as

Squeeze-off & gel patch repair methods for polyethylene pipe in natural gas distribution lines

Creator:: Harris, Kevin E.
Abstract:: The natural gas industry has become essential in many areas in the United States. Currently there is over 37.5 million miles of natural gas distribution lines. A large majority of these lines are polyethylene pipes. With such a large percentage of polyethylene lines in use gas companies are continually looking...

High-cycle fatigue response of diagonally-cracked conventionally reinforced concrete bridge girders

Creator:: Lee, Ae-young S.
Abstract:: The behavior of stirrups engaged by diagonal cracks and under service loads is largely unknown. Full-size laboratory specimens were loaded to induce diagonal cracks and subjected to high-cycle fatigue loading to represent a service life of 50 years. Tests indicated little change in the average stirrup stress range and mean...
