Development of Advancded Grid Stiffened (AGS) Fiber Reinforced Polymer (FRP) Tube-Encased Concrete Columns, Technical Summary.

摘要

In this project, a new type of confining device, a latticework of interlacing FRP ribs that are jacketed by a FRP skin, is proposed, manufactured, tested, and modeled to encase concrete cylinders. The objective of this study is to investigate the structural behavior of this novel advanced grid stiff ened (AGS) tube encased concrete cylinder through systematic experimental testing and finite element modeling. Parameters that determine the structural response will be evaluated. The fire resistance will be enhanced through nano-reinforcement. A life-cycle economic analysis will be conducted to evaluate the potential application of this novel column in bridge construction.
