Column Forces

This report provides the Dead Load, Live Load and Roof Live Load column forces at top and bottom of each column. When live load is skipped four separate live load cases are reported, namely:

Maximum Mmajor+, Maximum Mmajor-, Maximum Mminor+ and Maximum Mminor-. For example, the Max Mmajor + row represent the sum of all the column forces from all load cases which produced a positive major axis moment, likewise for the other rows. Refer to Section 3.5.1 for an explanation of how exactly the column forces are calculated. These forces are then combined with lateral forces in the column mode to produce the final design forces (see RAM Concrete Column Manual for more information).

The output is provided at the face of columns where they frame into beams top or bottom, or at centerlines otherwise. All live load values have already been reduced by the applicable live load reduction factors.

In the case of a hyperstatic column load being introduced by RAM Concept the reportmay show an additional hyperstatic set of forces.
