Abstract
This paper presents the hybridization of different types of fibers to overcome their shortcomings, to integrate their advantages, and to subsequently achieve the best performance-to-price ratio. In addition, through hybridization, the mechanical properties of the FRP composites can be tailored for specific applications. The behavior of hybrid FRP tendons was studied experimentally and analytically. Then, the behavior of partially pre-stressed FRP-RC deck slabs with the developed hybrid FRP tendons was experimentally investigated. Finally, numerical study on the pre-stressed FRP-RC bridge deck slab was conducted; the numerical study examines the macro and micro behavior of concrete bridge deck slabs reinforced with partially pre-stressed fiber reinforced polymers (FRP) bars under the effect of a concentrated load. Finally, a comprehensive parametric study was conducted.
