Abstract: This paper extends Keller's classic solution for the optimal design of columns to the case of plates. After the introduction of nondimensional variables, a calculus of variations technique is used to derive an optimality ...

Abstract: This technical note describes a computer program written to generate the member stiffness matrix for geometrically nonlinear space frames using the equations of three-dimensional (3D) beam-columns without cross-sectional ...

Abstract: This paper discusses shape-finding for cable nets and fabric structures through the use of nonlinear structural analysis computer programs rather than specialized “black box” software. Methods for shape-finding of membranes ...

Abstract: In the most simple case of plastic collapse, it is said that a hinge forms in a member when the moment capacity is reached. In the more complex case of plastic collapse, when the effect of axial load on the moment capacity ...

Abstract: This note describes some interactions that can occur between stress resultants in elastic, three-dimensional structures when geometric (beam-column) nonlinearities are considered. These effects generalize the well-known ...
