ALSO, ADJUST EDGE DISTANCE, CENTER TO CENTER BOLT SPACINGS, CLEARANCES, ETC.

13. FOR BOLT DIAMETER EQUAL OR GREATER THAN 1", THE HOLE DIAMETER SHALL BE „" PLUS DIAMETER OF BOLT.

12. OFFSET DECK JOINTS A MINIMUM 3'-0" FROM STEEL FIELD GIRDER SPLICES.

REQUIREMENTS.

11. DESIGNER TO VERIFY THAT BOLT SPACINGS FOR FLANGE SPLICES AND WEB SPLICES DO NOT EXCEED BOLT SEALING

10. THE EFFECTIVE COMPRESSION FLANGE AREA SHALL BE TAKEN EQUAL TO THE GROSS AREA OF THE COMPRESSION FLANGE.

CONSIDER A STAGGERED BOLT PATTERN.

IN CASES THAT A SIGNIFICANT REDUCTION IN FLANGE CAPACITY OCCURS DUE TO EFFECTIVE AREA,

WITH SPLICES IN HIGH MOMENT REGIONS.

THIS GIRDER CAPACITY CHECK IS CRITICAL FOR SINGLE SPAN STRUCTURES AND CONTINUOUS STRUCTURES

F = SPECIFIED MINIMUM YIELD STRENGTH OF THE FLANGE, ksi.

F = SPECIFIED MINIMUM TENSILE STRENGTH OF THE FLANGE, ksi.

0 = 0.95

0 = 0.80

A = GROSS AREA OF FLANGE, in.

A = NET AREA OF FLANGE, in.

NET AREA, A , IN ACCORDANCE WITH THE FOLLOWING:

9. CHECK GIRDER CAPACITY FOR REDUCTION DUE TO BOLTS HOLES IN THE TENSION FLANGE USING THE EFFECTIVE

COMPONENT BEING TOP FLANGE, WEB OR BOTTOM FLANGE.

8. CAPACITY OF COMPONENT SPLICE PLATE TO EQUAL CAPACITY OF COMPONENT.

7. DESIGNER TO INDICATE WHETHER OR NOT THE BOLTS ARE DESIGNED FOR THREADS EXCLUDED FROM SHEAR PLANE.

6. DESIGNER TO VERIFY INSTALLATION CLEARANCES AS ILLUSTRATED IN AISC MANUAL OF STEEL CONSTRUCTION.

TO OBTAIN A DESIGN WITH THE TYPICAL 2 OR 3 ROWS OF WEB SPLICE BOLTS.

TO MINIMIZE THE NUMBER OF GAGE LINES OF WEB BOLTS. THE DESIGNER SHOULD INCREASE THE WEB EDGE DISTANCE

THE DESIGN. THE DESIGNER SHOULD ADJUST THE WEB EDGE DISTANCES, INCREASING THE PLATE BEARING CAPACITY,

MAY BE SIGNIFICANTLY LESS THAN THE BOLT SHEAR CAPACITY RESULTING IN THE PLATE BEARING CAPACITY CONTROLLING

5. FOR THE MINIMUM EDGE DISTANCES, THE BEARING CAPACITY OF THE WEB PLATE, ESPECIALLY THIN WEB PLATES,

THIS WILL PROVIDE A TOLERANCE FOR PUNCHING, DRILLING AND REAMING.

CLEARANCE IN ACCORDANCE WITH STRUCTURAL COMMITTEE FOR ECONOMICAL FABRICATION DETAIL.

4. EDGE DISTANCES SHOWN ARE MINIMUMS BASED ON SHEARED OR GAS CUT EDGES PLUS AN ADDITIONAL ‚"

3. BOLT SPACINGS SHOWN ARE PREFERRED MINIMUMS.

2. DETAILS SHOWN ARE FOR ‡" DIAMETER HIGH STRENGTH BOLTS.
