Penetration Inside Middle Third of Beam

Elements

About this detail

Utility penetrations must be located within the middle third of the beam depth, maintaining a minimum vertical clearance of D/3 from both the top and bottom flanges. For multiple beam penetrations, openings are restricted to a maximum diameter of six inches and require a minimum clear horizontal spacing of two times the beam depth between adjacent openings or concentrated loads. Openings must be sized per mechanical, electrical, and plumbing engineering documents and positioned away from concentrated loads from supported beams or columns above.
