Abstract:
Flexural behavior of 28 beams was experimentally investigated with an emphasis placed on the determination of the effects of SIMCON addition on the flexural response of SIMCON retrofitted and SIMCON repaired concrete beams. The complete flexural behavior of SIMCON retrofitted and repaired beams is investigated and documented. All beams were subjected to third point flexural loading tests. A theoretical nonlinear analytical model and a simplified analytical approach were developed and proposed in this study. The full moment-curvature response was modeled and quantified. The experimental results obtained were compared to the results of the analytical and numerical solutions. The agreement between the analytical and experimental results was found to be very good and the assumptions made in the definition of the models and the analytical computations were verified. The software developed appears to be a viable tool for the prediction of the flexural behavior SIMCON-concrete composite.
