The paper describes the micro-wave network of telephone and television communication and the different forms of tower structures which are required for this system with particular reference to the tower buildings at London (Museum) and Birmingham. The design of these towers presents new problems in the assessment of the wind characteristics and aerodynamic stability of the structures. L.R. Creasy, H.C. Adams and S.G. Silhan
The classical plate theory equations are solved numerically for the case of a load distributed over a small area of an infinite circular slab on an elastic foundation. The results are compared with Westergaard’s solution and a simple design chart presented. W.E. Scriven and W.R. Pilgrim
Theoretical and empirical approaches to the problem of combined bending and torsion have been proposed by various investigators, notably Lessigl,2,3, Chinenkov4, Yudin5, Gesund6,7. Although a full understanding of the mechanism of failure does not exist, considerable advances have been made in recent years. The most elaborate approach which correlates theory with the mechanism of failure was by Lessig and the present investigation was carried out to study the behaviour and the mechanism of failure of hollow reinforced concrete beams under combined loading. A simplified theoretical approach has been evolved which predicts the strength of reinforced concrete beams fairly accurately. Professor R.H. Evans and S. Sarkar
