Reliability-Based Evaluation of Two-way Shear Design Reinforced Concrete Slabs with FRP Reinforcements

Abstract

The two-way shear design of slabs is being revisited by researchers all over the world, especially, those with fiber reinforced polymers (FRP) reinforcements. Recently, researchers are investigating the development of mechanical models with physical meaning. The validation of these models was conducted based on the model variability, while ignoring the testing measurements and the basic variables variabilities. In this study, a reliability-based evaluation of the current design codes and guidelines for two-way shear of concrete slabs with FRP reinforcements. The reliability analysis method included the model variability and the variability of basic variables. For evaluating the probability of failure, Reliability indices (β) are calculated and compared to each other. Concluding remarks were outlined and discussed.
