| Abstract | ||
| This paper is concerned with the development of computational model of nonlinear response of hybrid reinforced concrete beams using finite element method with layering technique. The degenerating shell element with material nonlinearity is used to analyze the beams. The area of steel reinforcement is represented by an equivalent thickness. Perfect bond between the concrete and reinforcement has been assumed. The elasto- plastic behavior of the steel is used. Both multilinear and elastic-perfect plastic models have been adopted to represent high-strength and normal concrete’s stress-strain behavior, respectively. A comparison between the proposed model and experimental results that published by other researchers have shown a good agreement. | ||
