Experimental and Numerical Comparison of the Concrete Slabs Reinforced with Composite Rebars

Abstract:

The evaluation of non-metallic reinforcing in slender concrete slabs is discussed in this article. The experimental campaign investigated the flexural behavior and the bending capacity of concrete slabs reinforced with Glass fiber reinforced polymer bars. A total of 6 slabs with a length of 1.36 m and cross-sectional dimensions of 0.50 x 0.04 m were tested until failure. The effective depth and reinforcement ratio are the same for all slabs. With an effective span of 1.3 m, the slabs were simply supported and tested in a four-point bending experimental setup. ATENA 3D, a finite element nonlinear solver, was used to simulate the experimental approach. The meshing was done using brick elements, and the calculation was performed with the Newton-Raphson method. The article compares the experimental program and nonlinear analysis performed in ATENA 3D program. The theoretical analysis outcomes are also introduced by calculating the deflection of the slab in the midspan. The correlation and a good agreement between numerical results and experimental outcomes are presented in the paper.
