UFC 3-300-10N
25 May 2005
2-3.9.6 Plant-fabricated metal-plate-connected wood trusses must be produced in
plants certified by the Truss Plate Institute (TPI) quality assurance inspection program
and must comply with the requirements of Section 2-3.11.
2-3.10
Metal Building Systems.
2-3.10.1 All metal buildings must be designed, detailed, fabricated, and erected in
accordance with the MBMA "Metal Building Systems Manual", and with the
requirements of Section 2-3.11.
2-3.10.2 Metal building systems that contain and support overhead cranes shall
comply with the requirements of Section 2-3-12.
2-3.10.3 The metal building fabricator must be certified through the AISC Plant Quality
Certification Program in the MB category.
2-3.10.4 The drawings provided to the metal building manufacturer must include the
following:
2-3.10.4.1 Complete dimensions that include such information as roof slopes, eave
heights, floor elevations, required clearances, outside face of girts or columns, and any
needed reference dimensions.
2-3.10.4.2 The nature, location, and magnitude of all loads and forces necessary to
design the superstructure, including all wind and seismic design requirements,
2-3.10.4.3 The design of the foundation and anchor bolts to resist all horizontal and
vertical loads imposed by the metal building framing system. This design information
shall be evaluated based on the foundation reactions provided by the metal building
manufacturer for review by the Structural Engineer of Record.
2-3.10.4.4 All serviceability limit states that are to be applied to the superstructure
2-3.10.4.5
Requirements and any design provision to accommodate future expansion
2-3.10.4.6
Acceptable locations for diagonal bracing.
2-3.10.5 Due to the relatively high lateral drift allowances for pre-engineered structures
in the MBMA specifications, the use of masonry veneers and masonry exterior
enclosures must be avoided for metal building systems unless the structural engineer-
of-record demonstrates by a relative stiffness analysis that the building displacements
and veneer backing displacements will not damage the masonry. Design and
construction of masonry veneers must comply with the requirements of
UFC 1-200-01 and ACI 530.
2-3.10.6 Metal building systems must not be attached to existing structures unless the
transfer of lateral loads into the existing structures has been accounted for in
modifications to the existing structural system.
