Next: Fluted Columns Up: Columns with Continuous Symmetry Previous: Columns with Continuous Symmetry Columns of Revolution -- Four TypesThere are four types of column with rotational
symmetry. Two types are periodic in the axial direction and two are not.
The nonperiodiccolumns may have a reflection symmetry in the horizontal
plane (
-- for example a column which is bowed out at the center) or not (
-- a column which widens at the base). See Figures
2 and 3.
The periodic columns of revolution may have an up-down
symmetry (
)or not (
).See Figures 4 and
5.
