Including Change 2, August 2006
All clay masonry must have a specified compressive strength (f'm) of not
less than 6.9 MPa (1,000 psi).
Provide control joints in masonry walls in accordance with NCMA Tek 10-
2B or Tek 10-3 and BIA Technical Notes 18A. The structural engineer must coordinate
with the architect to assure that the requirements for masonry control and expansion
joints are clearly shown on the construction drawings.
Concrete masonry unit foundation walls below grade must be completely
filled with grout.
Shear walls must use running bond construction.
Air spaces, cavities, chases, expansion joints, and spaces to be grouted
must be kept free from mortar and other debris.
Provide anchors and ties for cavity walls. Do not use corrugated metal
ties or ties with an integral drip in cavity walls.
Unless otherwise noted herein, all structural steel design and construction
must be in accordance with UFC 1-200-01.
Refer to FEMA 350, FEMA 351, FEMA 352, FEMA 353, FEMA 355, and
2002 AISC Seismic Provisions for Structural Steel Buildings for additional seismic
design guidance for structural steel buildings.
Structural steel fabrication and erection procedures must be in accordance
with AISC Code of Standard Practice.
Structural steel framing systems must be designed for vibration
serviceability due to human activity in accordance with AISC Steel Design Guide 11.
Provide Direct Tension-Indicating (DTI) washers at all bolted connections.
Any single panel point of the lower chord of exposed roof joists or trusses
or any point along the length of exposed primary structural members supporting roofs
over manufacturing, storage and warehousing, or maintenance shops must be capable
of safely supporting a suspended concentrated load of 8.90 kN (2000 pounds) in
addition to dead loads. For all other occupancies, a concentrated load of 0.89 kN (200
pounds) must be used instead of 8.90 kN (2,000 pounds).
All structural steel exposed to the weather must adequately protected to
prevent corrosion. All galvanized structural steel must in accordance with ASTM
A123/123M or ASTM A153/153M, as applicable. Galvanize after fabrication where
practicable. Repair galvanized coatings using ASTM A780 zinc-rich paint for
galvanizing damaged by handling, transporting, cutting, welding, or bolting.
