    "STEEL DIAPHRAGMS - AT CONTRACTOR’S OPTION, STEEL DIAPHRAGMS MAY BE USED IN LIEU OF THE CONCRETE DIAPHRAGMS SHOWN IN THE PLANS. AT A MINIMUM, STEEL DIAPHRAGMS ARE TO BE DESIGNED AT STRENGTH LIMIT STATE III WITH A THREE SECOND GUST WIND SPEED OF 140MPH APPLIED TO ONE HALF OF THE VERTICAL SURFACE AREA OF THE EXPOSED BEAM USING EXPOSURE CATEGORY D. CROSS FRAME CONFIGURATIONS SHALL HAVE A HORIZONTAL ANGLE OR CHANNEL AT EITHER THE TOP OR BOTTOM POSITION. STEEL DIAPHRAGMS SHALL BE MANUFACTURED BY A FABRICATOR LISTED ON QPL 60 PER SECTION 501 OR GREATER STEEL. ALL COMPONENTS OF THE STEEL DIAPHRAGM SHALL BE GALVANIZED ACCORDING TO ASTM A 123. CONNECTION BOLTS SHALL CONFORM TO ASTM F3125 (GRADE A325). NUTS SHALL CONFORM TO ASTM A563. WASHERS SHALL CONFORM TO ASTM F436. ALL HARDWARE SHALL BE GALVANIZED ACCORDING TO ASTM A153. STABILITY OF THE BEAMS AND STRUCTURE DURING ALL PHASES OF CONSTRUCTION ARE THE SOLE RESPONSIBILITY OF THE CONTRACTOR. SUBMIT SHOP DRAWINGS AND CALCULATIONS FOR THE STEEL DIAPHRAGMS TO THE ENGINEER FOR REVIEW AND ACCEPTANCE. THE USE OF STEEL DIAPHRAGMS SHALL BE INCLUDED IN THE PRICE BID FOR “LUMP-SUPERSTRUCTURE.”"
