Abstract:
In many problems associated with refined analysis and interpretation of experiments on reinforced concrete beam-columns, it is necessary to determine the strain distribu-tion in any section of the member from the bending moment and longitudinal force acting at that section. In the analysis which is presented in this paper, the strains are assumed to be linearly distributed in the cross section. Realistic stress-strain relations are used for both concrete and steel. A numerical scheme, the extended Newton-Raphson procedure, is applied to solve the problem in the general case. A numerical example is given to illustrate the method.
