    An investigation into the material behaviour of reinforced concrete beams
    (1988) Samaai, Mogamat Faldi; Martin, JB
    An investigation into the material behaviour of reinforced concrete beams is presented. This investigation is divided into two parts. First, the experimental load-deflection tests on eleven under-reinforced two-span- and four slightly over-reinforced simply-supported beams are presented. The finite element simulation of these beams using the program, NLFRAM is then presented. This is followed by a material parameter study. In this study, the sensitivity and numerical efficiency of the material models in NLFRAM is assessed. This is done by systematically varying the parameters in the material models and comparing the load-deflection results. The load-deflection results from these examples are compared with the experimental results. In this way, the accuracy of NLFRAM in simulating practical structures is examined. The results of these comparisons indicate that with the simple material models used in NLFRAM, numerical results which are cost effective and in good agreement with the experimental observations may be obtained
