Performance of Precast Concrete Bridge Girders with Externally Bonded Anchored CFRP
(2019-08-08)Repair with Carbon Fiber Reinforced Polymer (CFRP) has become a topic of great interest to engineers in the last two decades. Fiber Reinforced Polymer (FRP) is considered as one of the most popular and practical solutions ... -
PERFORMANCE OF RECYCLED PLASTIC PINS FOR INCREASING BEARING CAPACITY OF FOUNDATION SOIL
(2021-08-10)Mechanically Stabilized Earth (MSE) walls constructed on unsuitable foundation soil are prone to large deformation and bearing capacity failure. A variety of techniques can be applied to address this issue, such as removal ... -
Performance-based Plastic Design Of Earthquake Resistant Steel Structures: Concentrically Braced Frames, Tall Moment Frames, Plate Shear Wall Frames
(Civil & Environmental Engineering, 2011-03-03)It is well known that structures designed by current codes experience large inelastic deformations during major earthquakes. However, current seismic design practice in the U.S. is based on elastic structural behavior and ... -
PHOTOCATALYTIC AND PHOTOCHEMICAL DECOMPOSITION OF VARIOUS PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) IN WATER
(2021-08-12)Per- and polyfluoroalkyl substances (PFAS) are anthropogenic compounds comprised of a perfluoroalkyl backbone and a terminal functional group. Their detrimental health effects of in humans, like other halogenated chemicals, ... -
Physical and Mental Health Challenges of Construction Workforce Active in Extreme Weather Conditions
(2022-08-15)Construction sites continue to operate despite inclement weather, exposing workers to unpleasant working circumstances that can lead to various physical and mental health challenges. A thorough literature review yielded ... -
PLANNING, DESIGN, AND OPERATIONAL ANALYSIS OF UNDERGROUND FREIGHT TRANSPORTATION SYSTEMS WITH INDIVIDUAL AUTONOMOUS VEHICLES
(2018-08-09)Given the increases in freight transportation demand, the current infrastructure for freight transportation appears insufficient. Moreover, the future development of capacity for freight transportation infrastructure seems ... -
