Development Of A Model Of Productivity For Horizontal Directional Drilling (HDD)
(Civil & Environmental Engineering, 2011-10-11)
Horizontal Directional Drilling (HDD) is a growing method for installation of pipes in urban areas and where ever trenching is impossible or undesirable; such as in crossing rivers, lakes, and railways, and special areas ...
A Non-invasive Assessment Of Moisture Content Of Municipal Solid Waste In A Landfill Using Resistivity Imaging
(Civil & Environmental Engineering, 2011-10-11)
A bioreactor landfill is operated to enhance waste decomposition, gas production, and refuse stabilization. The fundamental aspect in the operation of a bioreactor landfill is the controlled addition of water and/or the ...
Unsaturated Soil Behavior Under Large Deformations Using A Fully Servo/suction-controlled Ring Shear Apparatus
(Civil & Environmental Engineering, 2011-07-14)
In recent years, the key hypotheses of most elasto-plastic constitutive frameworks postulated for unsaturated soils have been validated via suction-controlled oedometer, triaxial, and direct shear testing. These techniques, ...
Non-linear Finite Element Dynamic Analysis Of The Effect Of Compaction On Underground Conduits
(Civil & Environmental Engineering, 2010-03-03)
Construction loads are an important but often overlooked factor in underground pipe design and installation. Common compaction equipments used in pipeline construction can be a major contributor to pipe damage. To reduce ...
Nano-modified Cement Composites And Its Applicability As Concrete Repair Material
(Civil & Environmental Engineering, 2011-10-11)
Nanotechnology or Nano-science, considered the forth industrial revolution, has received considerable attention in the past decade. The physical properties of a nano-scaled material are entirely different than that of bulk ...
Development Of A True-cost Concept For Renewal Of Municipal Underground Pipeline Systems
(Civil & Environmental Engineering, 2012-04-11)
Asset management principles for underground pipeline infrastructure (UPI) are used by municipalities for efficient delivery of water, wastewater, and storm sewers. Due to budget constraints and limited resources, ...
Development Of A Model For Estimation Of Buried Large Diameter Thin-walled Steel Pipe Deflection Due To External Loads
(Civil & Environmental Engineering, 2013-07-22)
Design of buried pipeline systems involves solution of geotechnical and structural problems in addition to the hydraulics and mechanical issues. Just like any buried structure, it is of utmost importance to understand how ...
Investigations To Develop Field Stabilization Methods To Mitigate Surficial Slope Failures
(Civil & Environmental Engineering, 2013-07-22)
Surficial slope failures induced by rainfall have been studied for many years. Current research supported by The United States Army Corps of Engineers (USACE) is undertaken at the University of Texas at Arlington on two ...
Long-term Performance Of GFRP Reinforced Concrete Beams And Bars Subjected To Aggressive Environments
(Civil & Environmental Engineering, 2012-07-25)
The use of fiber-reinforced polymer (FRP) bars in reinforced concrete (RC) structures has emerged as an alternative to traditional steel reinforcement environments and other applications where steel has shown greater ...
On The Effects Of The Circular Bolt Pattern On The Behavior Of The Extended End-plate Connection
(Civil & Environmental Engineering, 2011-10-11)
This study is pioneer in introducing the circular bolt pattern configuration in extended end-plate steel connections. Discovering the static and cyclic behavior of such connections is at the forefront of this research ...
