Day 2: Slide Summary

Image Pairs Commentary
The structure of the large leaf and that of a "traditional" pre-motorization village show many similarities. Especially if one considers the structure of the major and minor paths of movement within the whole.
The geometric structures of the lansdcape do not reveal themselves until seen from far above. The perceptions of the structure are significantly altered depending on the time and place of the viewer. The forces which created the actual structure/artifact can only be inferred.
These two images of the structure of I.M. Pei's Louvre addition represent the effect that the nature of materials, and the understanding of the implications on the conception and method of construction, can have on a desgin.
The two most ancient structural types: the arch and the beam. These are two doorways of high Alpine hay storage "barns" in Switzerland. Notice the masses that are above each of the structures.
The surfaces of a structure effect the total load on the whole. These considerations come into play fromthe very first instance. A fired-tile roof has both inplications from an environmental standpoint as well as a load-bearing standpoint. In all cases it will have a larger load-bearing structure than the Tin Hau bamboo and sheet metal opera house from Hong Kong.
Understanding the structre of a material is critical to its appropriate use. Anisotropic materials will have differenct characteristics than isotropic. This can be, must be, utilized as a positive design reality.
Robert Maillart designed a number of bridges in Switzerland. The first was the Inn River Bridge by Zuoz, Graubunden. His designs were true expressions of form follows force.
Robert Wagner embraced the concept of "construction" as one of his design motifs. He exaggerated an expresion of the load-bearing structure in many of his buildings.
The Firth of Forth bridge in Scotland is one of the clearest examples of the way in which one bridge failure can influence the design of another. The elements of the bridge clearly represent the type and magnitude of the interanl forces.
This is the construction site of one of architect Prof. David Niland's beautiful houses near Cincinnati. No matter the type of structure, or it's size or material, the basic issues of strength and stability must at all times be considered.
