Research And Application On Ultimate Load Capacity Of Reinforced Concrete Beam By Layered F.E.M.

About the research on ultimate load capacity of reinforced concrete beam, it is the issue that people care about. In recent years, the scholars of various countries have carried some theory and research work of the test, but till at present, the deal to this problem still haven't a very good solution, need further analysis and study.This text on the basis of studying both at home and abroad, go on research on ultimate load capacity of reinforced concrete beam by layered F.E.M. This method is the result that a finite element of reinforced concrete analyses and layer theories combine together, we can think about the material non-linear question of reinforced concrete beam conveniently by this method.This text work out the finite element procedure on ultimate load capacity of reinforced concrete beam, and through the analysis to two existing reinforced concrete model beam, have proved the validity of the procedure. The result shows: Carry on ultimate load capacity of reinforced concrete beam with this procedure, the result of calculation has good precision; Meanwhile, this procedure can get the whole course that reinforced concrete beam destroyed.Utilize this procedure, carry on the analyse about ultimate load capacity of reinforced concrete beam in actual project, and contrast with the GF method result, draw difference of them, make us to the ultimate load capacity of reinforced concrete beam have a profound understanding, there is certain reference value in GF improvement of the design method and application of the actual project.
