|
Penetrations are similar to openings but are designed for smaller unframed openings in which the surface loads are unaffected. Penetrations have no effect on the surface load distribution; they are ignored when tributary loads and areas are calculated. They are modeled using the Layout - Slab - Penetrations command by entering the dimensions and location for each penetration on the layout type. |
The sole purpose of penetrations is to limit the effective flange width of composite beams in the RAM Steel Beam module. In composite beam design, the proximity of a penetration to a beam will be considered in the calculations of effective flange width. If a penetration falls on a beam, that beam will be designed noncomposite.
