Stresses and deflexions in castellated beams

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. J. KOLOSOWSKI
