History

The "whole idea" for this exquisite building, the british pavilion: Seville, Spain, was inspired by the expression of technological climate control, which seems hasty in buildings existing in Spain today. The locality of seville is quite extreme in clima te sense; for it is the hottest place in Europe. The need for such an exposition demanded a responsive architectural monument to minimize the heat which beats down on the sun baking building.


Physical Description

Its overall dimensions are 120 feet by 200 feet, with structural members that span vertically as well as horizontally. the flange width of the major members is 9 feet wide.

The sense that this place has been created to cool a larger space with the least amount of energy consomed within the building, has become it's essence. As a prefabricated structure, the pavilion contains various elements (structurally and architecturall y) to articulate and provide this climate control throughout the building. The most notable feature which helps do this is the water wall; it becomes an element which provides a visula and physical cooling effect, and an architectural motif which sets a tone to the building's character. the large glazed areas consist of the water running planar with the wall, and the water streaming off the structure, creating a more focused sense of the transparency of the skin.

Another element which helps the environmental control system of the building is the S-shaped solar/shading panels. These help the metal panels on the roof from getting too hot.

A PVC coated polyester fabric, fixed to the bow steel tubes, not only help the structural sense of the building, but also the additional protection against sunlight. Here, the pavilion expresses the structural elements either through the transparent enve lope, or the penetration of the structure throughout the building itself.

All of the joints in the structure are either pinned or bolted depending upon the connection used for application.

Structural Descripton/Aspects

Dead vs. Live Loads
The application of an inverted bow truss spanning the width of the building, and vertical truss members appearing at the sides of the structure define a fluent correlation of live and dead load distributions. The dead loads which act on the structure are the materials and physical features themselves from the roof, to the ground. These such things include, the panels on top, the bow truss, and the vertical trusses which hold up this entire system. The bow trusses on the ends are strictly for skin closu re to the structure, they do not in any way act as load bearing structural members to the pavilion.

The live loads, which include the wind loads and rain loads are important stability factors within the design. Other live loads do not apply inside the structure, due to the fact that there is an "infrastructure" (separate exhibition floors structurally independent from the envelope) within the pavilion.
