Epoxy Glass Fiber Reinforced Plastic Dowel Splice For Prestressed Precast Concrete Pile, Saman Farhangdoust
Epoxy Glass Fiber Reinforced Plastic Dowel Splice For Prestressed Precast Concrete Pile, Saman Farhangdoust
FIU Electronic Theses and Dissertations
Due to limitations in operation, shipping difficulties, and unforeseen soil conditions, it often happens that splicing of precast-prestressed concrete pile (PPCP) segments has to be performed at the construction site to achieve longer lengths. In order to splice PPCPs, Glass fiber reinforced polymer (GFRP), Carbon Fiber Reinforced Polymer (CFRP), and Stainless Steel (SS) dowels can be used as corrosion-resistant bars. In addition to their durability and superb mechanical performance, GFRP bars show cost advantage when compared to other corrosion-resistant materials. The objective of this study is to investigate the flexural behavior and effectiveness of the GFRP dowel and compare its …

A Model For Continuous Measurement Of Drilled Shaft Diameter During Construction, Masood Hajali
FIU Electronic Theses and Dissertations
Non-Destructive Testing (NDT) of deep foundations has become an integral part of the industry’s standard manufacturing processes. It is not unusual for the evaluation of the integrity of the concrete to include the measurement of ultrasonic wave speeds. Numerous methods have been proposed that use the propagation speed of ultrasonic waves to check the integrity of concrete for drilled shaft foundations. All such methods evaluate the integrity of the concrete inside the cage and between the access tubes. The integrity of the concrete outside the cage remains to be considered to determine the location of the border between the concrete …
