The load was appliedconcentrically through the axis of the column. Loads shown are validonly if there is uniform contact between the full area of column endsand the cap & base units. Loads are provided for your convenienceonly and are not exact values. Consult a structural engineer for themost accurate load estimates.Shaft Diameter Unfluted Fluted6" 1-1/2" 1-1/2"8" 1-1/2" 1-1/2"10" 1-1/2" 2"12" 1-1/2" 2"14" 2" 2"16" 2" 2"18" 2" 2"20" 2" 2"22" 2" 3"24" 2" 3"26" 2" 3"28" 2" 3"30" 2" 3"32" 3" 3-1/2"34" 3" 3-1/2"36" 3" 3-1/2"SUPERPOSITIONThe view of Renaissance authority Scamozzi was that the lowerdiameter of a top column should equal the upper diameter of thecolumn underneath. The superior order should always be placedover the inferior, that is Corinthian over Ionic, Doric, Tuscan. The moreslender and elegant orders should be placed over the stockier andmore solidly built if a top-heavy design is not desired. An ancientexample of this descending order is the Colosseum in Rome, whichhas at least four stories of superpositioned orders.PART 1: GENERAL1.1 SECTION INCLUDESA. Architectural wood columns.B.
