Bearing End Frame
Used at end walls of building where future expansion is not anticipated.  Framing members formed from hot rolled members.

Unless otherwise specified, all buildings have a Bearing End Frame at each end wall.  Rafters, corner posts, and end posts are either hot-rolled mill sections or welded-up H sections.  Rafter is designed as a continuous beam over end post supports and pin connected at corner posts.  End posts and corner posts are designed as simply supported, being pinned at both ends.  Frames are designed by computer analysis accordance with accepted engineering practices.  Since there is no rigid frame action at a Bearing End Frame, the lateral wind load from the half-bay tributary area acting on the frame is resisted by diaphragm action of the sheeted end wall, or by rod/cable bracing added in the plane of the endwall.

Width, eave height, roof slope, loading, and geometry (i.e. gable or single slope) of Bearing End Frames will be the same as primary frames in building.

End walls on bearing frame building have By-pass Girts as standard, with Inset Girts optional.  Inset Girts/flush Wall condition (where end post depth is limited to 9” to contain these columns entirely within the girt space) are also optional but may only be used on building whose peak height does not exceed 35ft.
