Field And Experimental Studies To Assess The Performance of Stabilized Expansive Clay
(Civil & Environmental Engineering, 2007-08-23)
A vast majority of the expansive soils are montmorillonite-rich clays, over consolidated clays and shales. The swell and shrinkage movements of expansive soil cause considerable damage to structures such as buildings and ...
Nonlinear Finite Element-based Investigation Of The Effect Of Bedding Thickness On Underground Pipe
(Civil & Environmental Engineering, 2007-08-23)
The pipe-soil interaction is studied by using the finite element software, ABAQUS/CAE Version 6.5-1 as a symmetric model of embankment installation to study the effect of bedding property and thickness on pipe-soil interaction ...
Vehicular Emissions Models Using Mobile6.2 And Field Data
(Civil & Environmental Engineering, 2007-09-17)
Regression models to predict vehicular emissions for different categories of vehicles for different pollutants are presented in this thesis. Vehicular emissions are affected by numerous variables which, among others, include ...
Analysis Of Hat Sectioned Reinforced Composite Beams Including Thermal Effects
(Civil & Environmental Engineering, 2007-08-23)
A simple analytical method for analyzing fiber reinforced polymeric composite beams with hat cross-section is presented. The method includes development of closed-form expression of the axial, bending and their coupling ...
Permeability Of Municipal Solid Waste In Bioreactor Landfill With Degradation
(Civil & Environmental Engineering, 2007-08-23)
Bioreactor landfills are operated and controlled to accelerate refuse decomposition, gas production and biological stabilization of the municipal solid waste (MSW). Leachate recirculation in bioreactor landfill creates a ...
Experimental Investigation Of Shear Capacity Of Precast Reinforced Concrete Box Culverts
(Civil & Environmental Engineering, 2007-08-23)
This study presents the experimental investigation of the shear capacity of four precast rinforced concrete box culverts. Each culvert was subjected to a monotomically increasing load through a 20-in x 10-in load plate, ...
Dynamic Chracteristics And Stability Analysis Of Muncipal Solid Waste In Bioreactor Landfills
(Civil & Environmental Engineering, 2007-09-19)
Bioreactor landfills are operated to enhance refuse decomposition, gas production, and waste stabilization. The major aspect of bioreactor landfill operation is the recirculation of generated leachate back through the ...
Effects Of A Debonding Flaw Size And Location On The Flexural Performance Of CFRP Retrofitted Steel Sections
(Civil & Environmental Engineering, 2007-10-08)
In US there are several thousand steel bridges at present. Out of them many bridges are at various level of advance deteriorations due to many years of service life and environmental factors. These bridges cannot be fully ...
Investigation Of Bamboo As Reinforcement In Concrete
(Civil & Environmental Engineering, 2007-08-23)
This study investigated the feasibility of using bamboo as a reinforcement alternative to steel in concrete structural members. The specifications studied were the bamboo's tensile strength and its pullout characteristics ...
Roadway Shallow Water Flow Modeling By Velocity Distribution
(Civil & Environmental Engineering, 2007-09-17)
Manning's equation is a widely used method for determining flow discharge in a channel with unconfined gravity flow. The roughness value, n-value, is a critical factor for Manning equation to obtain the accurate amount of ...
