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 ...
Studies On Field Stabilization Methods To Prevent Surficial Slope Failures Of Earth Fill Dams
(Civil & Environmental Engineering, 2009-09-16)
Surficial failures are occurring frequently on the slopes of earthfill dams which are predominantly rainfall induced. Desiccation cracks form on the slope surface during dry environment which accelerates infiltration during ...
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 ...
Dynamic Properties Of Compacted Soils Using Resonant Column With Self-contained Bender Elements
(Civil & Environmental Engineering, 2008-08-08)
A comprehensive series of resonant column and bender elements tests were simultaneously performed in the developed RC/BE apparatus. RC/BE tests were conducted on compacted specimens of poorly graded sand (SP) and high ...
Modeling Unsaturated Soil Response Under Suction-controlled Multi-axial Stress States
(Civil & Environmental Engineering, 2008-04-22)
In this research work, a novel suction-controlled true triaxial testing apparatus has been developed to test 3-in (7.5-cm) side, cubical specimens of unsaturated soil under controlled-suction states for a wide range of ...
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, ...
Deep Mixing Technology For Mitigation Of Swell-shrink Behavior Of Expansive Soils Of Moderate To Deep Active Depths
(Civil & Environmental Engineering, 2008-04-22)
Expansive soils are well known for their cyclic shrink-swell behavior due to seasonal related moisture changes. These cyclic movements of expansive soils are due to physico-chemical changes at particle level that are ...
Experimental And Field Monitoring Studies On Recycled Materials As Pavement Bases
(Civil & Environmental Engineering, 2008-04-22)
Natural aggregates derived from a variety of source rocks have been used as a road base material. But the extraction of natural aggregates resources is increasingly being constrained by urbanization, increased costs and ...
