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

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...
Resource Type:: Dissertation
Full Text:: (NLFEM). Results indicate the repair methods increased the member strength and the predicted member

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...
Resource Type:: Dissertation
Full Text:: regular maintenance, upgrading, and road removal. The first chapter describes the challenges

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...
Resource Type:: Dissertation
Full Text:: Transaxle • Engine Repair • Heating and Air Conditioning • Manual Drive Train and Axles

Setting forest road maintenance and upgrade priorities based on environmental effects and expert judgment

Creator:: Coulter, Elizabeth Dodson
Abstract:: The prioritization of road maintenance projects is an important forest engineering task subject to limited budgets and competing investment needs. Large investments are made each year to maintain and upgrade forest road networks to meet economic and environmental goals. Many models and guidelines are available for single-criterion analysis of forest...
Resource Type:: Dissertation

Study of multi-criteria decision-making : development of a decision model to determine when to conduct nighttime construction road work

Creator:: Park, Sang-Bin
Abstract:: Many Departments of Transportation (DOTs) have done construction and maintenance work at night in order to minimize the disruption of daytime traffic, but nighttime operations produce a new set of concerns such as safety, public relations, productivity, and work quality. In addition, decision-making for using nighttime operations has been subjective...

Nonlinear finite element analysis of reinforced concrete structures strengthened with FRP laminates

Creator:: Chansawat, Kasidit
Abstract:: The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...

Minimizing total cost of construction, maintenance, and transportation costs with computer-aided forest road design

Creator:: Akay, Abdullah Emin
Abstract:: The systems currently available for forest road design are not capable of making computer-aided design judgments such as: 1) automated generation of alternative grade lines, 2) optimizing vertical alignment, 3) minimizing total cost of construction, maintenance, and transportation costs, and 4) aiming for least environmental impacts. In recent years, advances...

A methodology to solve large-scale group fleet replacement problems

Creator:: Somboonwiwat, Tuanjai
Abstract:: This research addresses the large-scale group fleet replacement problem with multiple vehicle types of multiple units, under budget and demand constraints. Past research in group fleet replacement is limited and has focused on one vehicle type, with multiples units and constraints. Many studies in fleet replacement have also dealt with...
Resource Type:: Dissertation
Full Text:: replacement decision include the purchase costs of new vehicles, operating costs, maintenance costs, and

An economic analysis of the short-run demand for timeliness with special reference to farm machinery parts

Creator:: Eiler, Doyle A. (Doyle Alden)
Abstract:: This thesis is an attempt to develop a theoretical microeconomic model which can be used to examine the short-run demand for the timeliness of farm machinery repairs. This analysis focuses on the timing of the repair after a breakdown has occurred. The nonstochastic model developed allows the incorporation of the...
