NOVEL INFRASTRUCTURE MONITORING USING MULTIFACETED UNMANNED AERIAL VEHICLE SYSTEMS - CLOSE RANGE PHOTOGRAMMETRY (UAV - CRP) DATA ANALYSIS
(2018-12-06)Remote sensing is a method of collecting data without making any physical contact with the object under inspection. Modern day remote sensing kicked off with the invention of the camera and continued on to the invention ... -
Novel Stabilization Methods For Sulfate And Non-sulfate Soils
(Civil & Environmental Engineering, 2009-09-16)Expansive soils are commonly found in arid and semi-arid climate zone. These soils typically exhibit moderate to high plasticity, low to moderate strength, and high swell and shrinkage characteristic which in turn result ... -
NUMERICAL AND EXPERIMENTAL INVESTIGATION OF BURIED LARGE-DIAMETER STEEL PIPES WITH CONTROLLED LOW-STRENGTH MATERIAL
(2016-08-12)The main goal of this research was to gain an in-depth understanding of the behavior of buried large-diameter pipes with controlled low-strength material (CLSM). Design equations were developed based on extensive parametric ... -
Numerical Modeling Of Ground Movements Associated With Trenchless Box Jacking Technique
(Civil & Environmental Engineering, 2014-09-17)The Trenchless Technology (TT) is defined as a family of methods used to install, renew, replace or renovate new pipe/box or existing pipe/box underground with little or no surface disruption. TT is divided into two main ... -
Numerical Simulation of Hydrodynamic Forces on Riverine and Coastal Bridges Subjected to Extreme Weather Events
(2023-01-02)Recent bridge failures due to hurricane-generated storm surges and riverine flood events have highlighted the vulnerability of bridge infrastructure to extreme hydrodynamic loading. In addition to posing an immediate risk ... -
