· Use two wheel loads representing an axle of a design truck applied 15’ from the
girder supports.
· The transverse spacing between the wheel loads was 6’, as specified in the
AASHTO Standard Specifications for Highway Bridges ( 1998).
· Each wheel load was applied as point loads applied in the nodes of a 10” × 20”
contact surface area.
The finite element model analyzed with the ANSYS software is presented in the Figure
3.2, and the batch input file is enclosed in the Appendix A.
Figure 3.2 ANSYS Finite Element Model
Two element types were used in the numerical model, the SOLID65 for the concrete
elements, and the LINK8 for the prestressing strands. The SOLID65 element includes
the GFRP rebars in the form of smeared reinforcement. SOLID65 is used for the 3- D
modeling of solids with or without reinforcing bars ( rebar). This solid is capable of
cracking in tension and crushing in compression. In concrete applications, for example,
