The suggested method is not limited to any special case or physical assumptions. Therefore, the linear stiffness matrix is inverted once at the beginning of the analysis. The stiffness matrices are generated distinctly for all mentioned parts. The solution procedure of each test is based on the division of degrees of freedom into three parts: (1) predefined lateral displacement of joints, (2) vertical displacement of joints, considered as linear degrees of freedom, and (3) rotation of joints, regarded as nonlinear degrees of freedom. Each numerical test consists of imposing prescribed displacement fields on the lateral displacement of stories and calculating the reactions of the structure. Here, the instantaneous reduced stiffness matrix of the structure is calculated, considering its linear behavior at the latest state, by performing a set of numerical tests on the whole structure. This algorithm can properly be used in nonlinear static analysis or in the incremental response spectral method. This paper addresses a numerical algorithm for nonlinear analysis of frames, using the unit displacement method, in generating a reduced stiffness matrix of the structure.
