STRUCTURAL GLASS FACADES - USC School of Architecture

Chapter 6 - Categorization and Organization of
Materials, Processes and Systems
Chapter 2 discussed in general terms attributes of the various materials, processes, and
system types that comprise structural glass façade technology. This Chapter will
categorize the structural systems, glass types, and glass systems that make up the
technology. A strategy for categorization is defined, and each system type is addressed.
A distinct set of evaluation criteria is developed for each of the primary systems;
structure type, glass type, and glass system type. Each categorized element is then
evaluated with respect to the appropriate criteria. The resulting attributes provide a
detailed basis for comparison between the categorized items.
The identification of a body of completed works comprised of glass-clad façade
structures with certain differentiating attributes as characterized herein has been
hypothesized as representing a unique building technology. Certain evidence has been
provided in this regard. A core test of this hypothesis will be the development of a
rational organization and categorization scheme for the elements perceived as
comprising this technology. The hypothesis further states that this body of façade
constructs is best categorized by the integral structural systems supporting the facades.
Secondary elements of glass and glass system are recognized as lesser opportunities
for such treatment. The discussion in this Chapter will be limited to brief system
descriptions, categorization issues, and comparative analysis of the defined classes. An
expanded discussion of the structural system, glass and glass system types is included
in Chapter 2.
