Sidesway
With the
command, the user can indicate whether a frame is Non-sway, Sway Sensitive, or Non-Sway on Axis. Non-Sway on Axis refers to structures that are Non-Sway in one direction but Sway-sensitive in the other. When Non-Sway on Axis is selected, the user must specify the range of member orientation, with respect to the global coordinate axes, for which the member is to be considered non-sway.K Factor
With the
command, major and minor effective length factors are set for the beams, columns and braces in the structure. The K factor only applies to the calculation of axial capacity for members loaded with axial load.Modifying the K-Factor criteria after a Code Check has been performed will invalidate the results of that Code Check. The model will be redrawn on the screen in its original colors (rather than the Code Check colors) indicating that the Code Check must be re-run.
Refer to the Assign chapter for information on how this criterion can be overridden on a member-by-member basis.
Flange Bracing
With the
command, the bracing condition of beams and columns is defined. Beam flanges can be braced continuously along the top flange, continuously along the bottom flange or not braced. Column flanges can be defined to be braced by the deck, by the beams that frame in within a given angle of a given column face, or not braced.Modifying the Flange Bracing criteria after a Code Check has been performed will invalidate the results of that Code Check. The model will be redrawn on the screen in its original colors (rather than the Code Check colors) indicating that the Code Check must be re-run.
Refer to the Assign chapter for information on how this criterion can be overridden on a member-by-member basis.
Beams with End Connections
RAM Frame performs a check of all beams with the following end connections: Standard, Spring, Custom, Reduced Beam Section (RBS), SidePlate® , DuraFuse®, and Yield-Link®. Refer to Assign - Beam Connection Types for details.
