Abstract
The method of Munro and Da Fonseca uses a fixed, arbitrary mesh of potentia l yield-lines to predict the collapse load of a slab or plate. This paper d escribes an optimisation procedure for adjusting the mesh to provide a safe r estimate of the collapse load. The paper is mainly devoted to practical e xamples illustrating the application of the technique. (C) 1998 Elsevier Sc ience Ltd. All rights reserved.
