Field Transfer Matrix for Nonlinear Curved Beams
Publication: Journal of Structural Engineering
Volume 114, Issue 3
Abstract
For large‐displacement and small‐strain analysis of planar general arches, the field transfer matrix is formulated for a curved element applicable to arbitrary arch geometry. The total displacements are clearly separated into the large rigid‐body displacements and the small elastic deformations. The formulation includes no approximation except the assumed small deflection theory for the elastic deformations. To establish a general computational strategy, however, the initial arch configuration is assumed to be accurately represented by using blending functions. No special shape functions for displacements are needed. The formulation is shown to be simple and accurate in theory and useful in practice.
