Behavior and Analysis of Economically Reactive Powder Rc Beams

A study for the load deflection behavior of reinforced beams cast using reactive powderconcrete RPC – as an ultra high strength concrete type - was executed experimentally and analytically. The experimental program was carried out to study the effect of cementcontent, using steel fiber and using two types of reinforcement. Results showed positiveeffect on cracking and ultimate loads of reactive concrete beams due to increasing of thecement content. The ductility of the reactive concrete beams is increased by using steelfibers. An analytical study was performed using a nonlinear computer program based onfinite element technique. A comparison between analytical and experimental results wascarried out to evaluate the efficiency and the accuracy of the used nonlinear computerprogram. The computer program results were practically close enough to the experimental results. The numerical analysis with the chosen finite element method presented a good simulation to the RPC beams.
