For the purpose of analyzing reinforced concrete frame works, an analytical method is presented here. Until now, most analytic methods which consider bond-slip or shear deformation of beam-column joints have been 2-dimensional methods, such as the finite element method. Some researchers have made use of beam theory taking into consideration shear deformation of beam-column joints. Others have made use of finite segment method taking into consideration bond-slip. But there have been few analysis of reinforced concrete frame structures taking into consideration the continuity of steel reinforced elements among beam, column and beam-column joint. The author has reported on the analytic method using finite segment method which considers bond-slip of reinforcing bars. In this paper, we wish to report on the method that considers the shear deformation of beam-column joints and the continuity of reinforcing bars among beam, column and beam-column joint. The non-linear method discussed in this paper is the incremental method, also referred to as the initial stress method, which has developed on a basis of the stationary principle of incremental potential energy. We have analyzed a cross-shaped R/C frame construction. Our results compared favorably with experimental data on load-deflection, and strain distribution of reinforcing bars.
