The Structural Engineer, Volume 63, Issue 6, 1985
Brick cladding for steel frames Dr. John Morton of the Brick Development Association has written seeking the assistance of our readers: For some years now, we have had many technical inquiries concerning brickwork used as a cladding to steel framed buildings. This subject has now moved up our programme of work, and a publication is to be prepared on brick clad steel framed buildings. Outside consultants are to be used to write this booklet, which is concerned with single and multistorey structures, the brief for which has been written by BDA and British Steel Corporation-the two joint sponsors.

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
