PART 2 - PRODUCTS

2.1 SYSTEM PERFORMANCE

A. Design structural steel framing connections complyi ng with specified performance:

1. Configuration: Design and detail all connections fo r each member size, steel grade and connection type to resist the loads and reactions indicated on the drawings or specified he rein. Use details consistent with details shown on drawings, suppleme nting where necessary. The details shown on drawings are concep tual and do not indicate the required weld sizes or number of bolts unless specifically noted. Use rational engineering design and standard practice in detailing, accounting for all loads and eccentricities in both the connection and the members. Promptly no tify the COR of

05 12 00 - 4 any location where the connection design criteria i s not clearly indicated. The design of all connections is subject to the review and acceptance of the COR.

2.2 MATERIALS

A. W-Shapes:

1. ASTM A992/A992M.

B. Channel and Angles:

1. ASTM A36/A36M.

C. Plates and Bars:

D. Bolts, Nuts and Washers: Galvanized for galvanized framing and plain finish for other framing.

1. High-strength bolts, including nuts and washers: A STM F3125.

2. Bolts and nuts, other than high-strength: ASTM A307 , Grade A.

3. Plain washers, other than those in contact with hig h-strength bolt heads and nuts: ASME B18.22.1.

E. Welding Materials: AWS D1.1, type to suit applicati on.

2.3 FABRICATION

A. Fabricate structural steel according to Chapter M, AISC 360.

B. Shop and Field Connections:

1. Weld connections according to AWS D1.1/D1.1M. Welds shall be made only by welders and welding operators who have been previously qualified by tests as prescribed in AWS D1.1 to per form type of work required.

2. High-Strength Bolts: High-strength bolts tightened to a bolt tension minimum 70 percent of their minimum tensile strengt h. Tightening done with properly calibrated wrenches, by turn-of- nut method or by use of direct tension indicators (bolts or washers) . Tighten bolts in connections identified as slip-critical using Di rect Tension

Indicators. Twist-off torque bolts are not an accep table alternate fastener for slip critical connections.

2.4 FINISHES

A. Shop Priming:

1. Prime paint structural steel according to AISC 303, Section 6.

B. Do not paint:

1. Surfaces within 50 mm (2 inches) of field welded jo ints.

05 12 00 - 5

2. Surfaces indicated to be encased in concrete.

3. Surfaces receiving sprayed on fireproofing.

4. Beam top flanges receiving shear connector studs ap plied.

C. Structural Steel Galvanizing: ASTM A123/A123M, hot dipped, after fabrication. Touch-up after erection: Clean and wir e brush any abraded and other spots worn through zinc coating, includin g threaded portions of bolts and welds and touch-up with galvanizing re pair paint.

1. Galvanize structural steel framing installed at ext erior locations.

D. Bolts, Nuts, and Washers Galvanizing: ASTM F2329, h ot-dipped.

2.5 ACCESSORIES

A. General: Shop paint steel according to AISC 303, Se ction 6.

C. Maintain erection tolerances of structural steel wi thin AISC 303 requirements.

1. Pour Stop Elevation Tolerance: 6 mm (1/4 inch), max imum, before concrete placement.

D. Weld and bolt connections as specified for shop con nections.

3.2 FIELD PAINTING

A. After welding, clean and prime weld areas to match adjacent finish.

B. Touch-up primer damaged by construction operations.

C. Apply galvanizing repair paint to galvanized coatin gs damaged by construction operations.

3.3 FIELD QUALITY CONTROL

A. Record Survey:

1. Measure and record structural steel framing plumbne ss, level, and alignment after completing bolting and welding and before installation of work supported by structural steel.

2. Identify deviations from allowable tolerances speci fied in

AISC Manual.
