This paper examines the limitations of methods used almost universally for the calculation of wind loads on vertical and horizontal latticed structures. As a result of difficulties experienced in the application of these methods to the design of cranes, a comprehensive review of past wind-tunnel tests, supplemented by additional testing, has been undertaken. The results have led to the formulation of new methods of design which are applicable to a wide range of latticed structures and also cover non-orthogonal presentations to the wind. J.F. Eden, A.J. Butler and J. Patient
The ‘one off’ approach to the design and construction of a multiplicity of buildings of similar use, size, design specification, and finish, together with the potential for standardisation of some types of structure, has been in the minds and thoughts of many involved in the construction of buildings. This has received some official recognition in the setting up of organisations such as CLASP, SCOLA, NBA, etc. L.E. Nowell
The response of an initially curved cantilever strut with a lumped mass at the tip subject to arbitrary axial impact loads is described, as a model for the dynamic response of unrestrained piles during driving. The differential equation of motion defining the lateral movement of impact-loaded cantilever struts is derived. This equation includes the effect of inertial resistance to motion provided by both the strut self-mass and the mass of the pile hammer. The shape of force pulses produced during pile driving was approximated by an equivalent trapezoidal force pulse. The differential equation of motion was solved for this force pulse using the Runge-Kutta technique. The solution was found to agree with observed pile behaviour during driving. It is shown that the magnitude of lateral displacements reduces as the mass of the pile hammer increases, because of inertial effects. R.C. Cugley, B. Kennedy and R.E. Melchers
