Web Moment Connection - Rat Hole tab

Used to set the rat hole consists of web and flange gaps, bevels applied to the flanges and access holes applied to the web.

Note: To enable Rat Hole settings, ensure the Beam Between Moments is unchecked.

Setting	Description
Rat Hole	When checked, a Rat Hole is applied end of the connecting member. Web Gap – Sets the gap from the end point of connecting shape to the web. Note: This distance is in addition to the gap between the connecting and supporting members. Flange Gap (Upper / Lower) – Sets the gap (additional distance) from the end point of connecting shape to the flanges. Upper / Lower Depth – Sets the depth of the bevel applied to the flanges. Upper / Lower Angle – Sets the angle of the bevel applied to the flanges. Invert (Upper / Lower) – When checked, the bevel is inserted on the opposite side of the flange. Chamfer/ Fillet/ Cope (Inserted Arc) – When checked, sets the respective type of cut for the access hole applied to the web. Upper/ Lower Chamher – For `Chamfer` option, the value equally sets the rise and run of the chamfered access hole applied to the web. Upper/ Lower Radius – For `Fillet` and `Cope` options, the value sets the radius of the access hole applied to the web. Upper/ Lower Web Distance – For `Cope` option, this value allows the access hole to be shifted to the right or left relative to the Web Gap.
Web Plate	Note: This option is only available when the Moment plates are inline with the flanges or not used at all. Upper / Lower Plate – When checked, sets the upper/lower or both weld plates be placed below the flanges. Length/ Width / Thickness – Sets the length, width and thickness respectively of the weld plates. Enabled when one of the weld plate or both options are set.
