NONLINEAR ANALYSIS OF PLANAR FRAMES WITH SEMI-RIGID CONNECTION

Abstract

In this study, the effects of connections and geometric nonlinearities on the behaviour of planar frames are examined. For this purpose a computer program has been prepared in FORTRAN77 language. If the load on the system renders the determinant of the tangent stiffness matrix negative, the program determines the critical load factor. The Richard Model is used for the nonlinear M-r relation of the connections and the behaviour of the material is assumed to be linearly elastic. The tangent stiffness matrix of the second order analysis is obtained from the solution of the linear differential equation governing the moment-curvature relation of a one-dimensional member in which the effects of axial force and semi-rigid connections are accounted for. In this method, the loads are applied step by step. The unbalanced forces are checked at every step of loading and the iteration is repeated until they are below a predefined tolerance. By means of these operations the errors due to the linearization of the nonlinear analysis is minimized.
