Abstract

This study focuses on assessing the accuracy of the stress-strain model of concrete, as per the fib model code 2010, in simulating the behavior of deep beams made of reactive powder concrete (RPC). RPC is a modern concrete classified as an ultra-high performance fiber reinforced concrete. The study utilizes finite element analysis (FEA) to obtain numerical results for deep beams and compares them with experimental data gathered from existing literature. The investigation involves three types of deep beams: normal strength concrete (NSC), high strength concrete (HSC), and RPC, allowing for comprehensive comparisons. The findings from the FEA reveal that the fib model code 2010 provides conservative estimations for the loading capacity of RPC deep beams. Consequently, it is recommended that a stress-strain model specially tailored for RPC be implemented to achieve simulation results that closely align with experimental results.
