Abstract
Concrete has been considered as the most widespread construction material due to its sustainability, low cost, and energy efficiency. However, the quick deterioration of concrete structures requires a repairing/strengthening them to possibly resist the initial design load. This research work performs a numerical study on composite beam containing conventional concrete (CC) and high-performance fiber-reinforced concrete (HPFRC). The HPFRC, which has been characterized by significantly greater mechanical properties but higher cost in comparison to CC, could be placed at an extreme compression of an RC beam to enhance its flexural resistances. The constitutive material properties under compression and tension of these concretes were firstly modeled based on experimental responses, and, they were then employed in ATENA software for the simulation of the composite beams. In evaluating flexural resistances of the composite beams, the simulated results revealed a good agreement compared to the experimental results provided in previous study.
