Ultimate Strength Analysis of Curved I‐Beams
Publication: Journal of Engineering Mechanics
Volume 109, Issue 1
Abstract
A method of analyzing the elastic and inelastic large‐displacement behavior of horizontally curved I‐beams based on the transfer matrix method is presented. The field transfer matrix is derived under the assumption that the elastic core in each segment is constant and the resultant force in the yielded portions of the cross section is replaced by the external force. The point transfer matrix is derived using the continuity of the displacements and the principal of virtual work taking into account the discontinuity of centroidal lines at the nodes. A computer program based on this theory has been developed and the theoretical values for the deformation and the ultimate strengths are shown to be in good agreement with experimental results. Some numerical examples are also presented. The effects of cross‐sectional dimensions, loading conditions, and residual stresses on the ultimate strength are analyzed for specified central angles of curved beams.
