portal (double column) type. As can be readily seen, the structural pat-
tern appears to be very complicated, although it contains, as enumer-
ated below, much more valuable information than that in the functional
description.

1. Fundamental shapes and main functions of structural units
2. Adjacent relationships between both structural units, i.e., inflow and
outflow surfaces of force in a structural unit
3. Number of structural units configuring a whole structure and their
allocation in three-dimensional space
