Web Crippling Parameters

This window is displayed when you select Web Crippling from the Compute menu, and the active window is a section. After you enter the appropriate values, press the OK button and the Web Crippling output will be displayed.

Load Applied ToThis is the surface of the section that the concentrated load or reaction is applied to. Select from Bottom Flange, Top Flange, Left Flange, Right Flange.
Concentrated Load or ReactionThe magnitude (factored for LRFD) of the load applied to the flange.
Moment at Point of LoadThe moment (factored for LRFD) in the member about the axis of bending under consideration. If the load is applied to the top or bottom flange, this moment should be the moment about the X axis. If the load is applied to the left or right flange, this moment should be the moment about the Y axis.
Bearing LengthActual length of bearing for the applied load or reaction.
Flange fastened to supportIndicates whether the bearing flange is fastened to the support. This can affect the web crippling strength.
Distance from edge of bearing
to end of member
The distance along the member from the edge of bearing to the end of the member. If the bearing is close to the end of the member, the web crippling strength is lower.
Distance from edge of bearing
to edge of opposite load
The distance along the member from the edge of bearing to the edge of a load applied to the opposite flange of the member. If an opposing load is near this load, the web crippling strength could be lower. If there is not an opposing concentrated load, then enter a distance of several times the member depth.
