Wind Pressures on the CAARC Standard Building Model : (P. Carpenter)
There is surprisingly little published data for basic measured pressure on simple building shapes in idealised wind conditions. This paper therefore aims to add to the available data, and to highlight interesting features of the complex pressure distribution patterns which occur for even a very simple building design. The highest design pressures typically occur at locations where peak suctions are measured. However , the distorting influences of different design wind speeds, velocity and turbulence profiles, building shapes, and surrounding buildings, make it difficult to compare results for different buildings or different wind tunnels.
Current Evolution of Tall Building Structures : (R. Tomasetti)
This paper reviews various approaches to the design of tall buildings in recent years. Design concepts utilizing steel, concrete and composite construction illustrate respective advantages. The evolution of design concepts which have led to the design of the tallest buildings in the world is discussed considering both static and dynamic structural behaviour. The contribution the structure can make to overall building design, function, space utilisation and economy is also discussed. In addition, some interesting problems in current high-rise technology illustrate unique challenges for structural engineers.
Soil Structure Interaction Analysis using the Boundary Element Method : (P. Waugh)
Soil structure interaction is a complex mechanism. It is usually modelled with a Winkler Model which unfortunately lacks the coupling due to shearing action of real soil. The Boundary Element Method (BEM) is a superior way of modelling soil structure interaction. The method is described and the formulae for vertical settlement soil structure interaction are developed.

Trial and Adjustment in Cross-Section Analysis : (P.J. Thompson)
Explicit formulae are available to compute the loading on a given cross-section that causes a given distortion. Usually however, the known information includes the axial load, and often also other aspects of the loading. Thus the explicit formulae are used in trial and adjustment routines. This paper discusses those routines.
