Deformation of plane core systems consisting of vertical and horizontal cores, which are rigidly or hingedly interconnected in the assembly, is considered in the article. Building frames of industrial and civil buildings, the columns of which undergo eccentrical compression and geometrically nonlinear deformation, have been investigated. There arises a necessity to solve the issues of strength, rigidity and stability. An algorithm and a computer program for solving this issue is proposed. The basic system of the deflection method and its suppositions has also been applied. The solution indicated stable convergence. Dependability between internal stresses of the cross section has been determined with account of the arising deformations and the effect of the linear compressing force that provides the accounting of geometrical nonlinearity. The examples illustrating high accuracy of the dislocation determination for the deformed-compressed core and the crippling load of the core system have been given. Finite-difference method that allows employing the cores the rigidity of which vary within their length limits has been used. The stability of the building under the core increment has also been investigated. An algorithm and a computer program for a plane core system calculation made up of vertical or horizontal cores rigidly or hingedly interconnected in the assembly have been worked out. Auxiliary core offsets and displacements of the system core joints have been taken as the basic unknown variables that allow making calculations with pre-set safety factor, rigidity and stability. The proposed stepwise method of the core system calculation is notable for its simplicity for programming. As the calculations testify, this method provides high accuracy of solutions. The applied method of finite differences may serve as a prerequisite for taking physical non-linearity of reinforced concrete into account.
