Significant developments in techniques for analysing complex wall systems have occurred over the past 15 years. These developments are reviewed and the relative importance of various parameters is discussed. The behaviour and analysis of both plane and 3-D wallsystems is considered. I.A. MacLeod

Dr. Eastwood (Past President) : A matter of some interest is the behaviour of the inclined piles. Some of the piles are vertical and some inclined and all are attached to a fairly rigid frame at ground level. Thus the tops of the piles will move down bodily in a vertical direction under load, whilst the toes of the piles will move in the direction at which the pile is inclined. The toes of the piles will tend to move apart and the piles will bend. With the amount of settlement which is expected could this bending be sufficient to produce cracking of the piles?

The paper published in January in The Structural Engineer was written about two years ago. Since then I have conducted further tests and discussed my ideas with a number of lecturers and engineers, all of which has confirmed the conclusions drawn in the paper.
