The stresses and deflexions in a castellated girder are calculated by the simple theory of bending and by two methods in which it is assumed that the girder behaves as a Vierendeel truss. The calculated values are compared with experimental data and it
is shown that the simple theory of bending usually underestimates deflexions by 20 to 30 per cent and that the measured stresses at some points in the girder deviate appreciably from the calculated values. However, the Vierendeel truss analogy is shown to provide more reliable values.
A discussion meeting will be held on Thursday 9 January 1964 at the Institution, when the above subject will be under review.
Mr. A. Jennings, Lecturer in the Civil Engineering Department of the University of Manchester, writes: ‘The standard methods of solution of linear redundant structures are all formulated in terms either of the unknown forces or of the unknown displacements and use the flexibility or stiffness properties of the structure to effect a solution. The method of solution of free cable problems advocated in this paper is peculiar in that it does not formulate the analysis directly in terms of either the unknown displacements or the unknown forces, and no concept of stiffness or flexibility is introduced.
