000011251 520__ $$2eng$$aIn this study, it has been aimed to develop an algorithm that determines failure mechanisms and ductility capacities of 3D frames under earthquake loads with three components and a computer program which performs dynamic analysis according to this algorithm. The proposed analysis accounts for material, geometric and connection nonlinearities. Material nonlinearity have been modeled by the Ramberg-Osgood relation. While the geometric nonlinearity caused by axial force has been described by the use of the geometric stiffness matrix, the nonlinearity caused by the interaction between the axial force and bending moment has been also described by the use of the stability functions. The independent hardening model given by Kishi and Chen has been used to describe the nonlinear behaviour of semi-rigid connections.
