A�SCE Standard: American Society of Civil Engineers, Minimum Design <br /> Loads for Buildings and Other Structures . <br /> MBMA: Metal Building Manufacturer' s Association, Low Rise Building <br /> Sys�tems Manual, latest edition. <br /> Specifications� <br /> Structural Steel : AISC Manual of Steel Construction, Allowable Stress <br /> Design - Ninth Edition <br /> Structural Joints : AISC specification for structural joints using <br /> ASTM A325 or ASTM A490 Bolts <br />� Cold-Formed Steel : AISI Cold-Formed Steel Design Manual 1996 edition <br /> with 1999 Supplement . <br /> Welding: �iWS (American Welding Society) D1 . 1 for Structural Steel, <br /> AWS D1 .3 for Sheet Steel . <br /> CSA (Canaiian Standard Association) W59 & W47 .1 <br /> Bolts � <br /> As a standard, ASTM A325 (Type N) bolts are used as bearing type <br /> c�onnections . Occasionally, it may be necessary to use (Type X) bolts . <br /> It is ensiired that proper checking is done for this condition. ASTM <br /> A307 bolts; are used for secondary member connections. <br /> � <br /> High Strength Bolts : <br /> ASTM A325! � (Used where specified on drawings) . ASTM A325 bolts used <br /> oin rigid frame moment connections are designed as bearing type <br /> clonnections, and threads are included in the shear plane. Turn of the <br /> nl�ut method is to be used in tightening the high strength moment connection <br /> bolts . Special inspection of the tightening of these bolts is required <br /> a�s specifi!ed on building codes . <br /> � <br /> � <br /> Welding: <br /> � Welds joining flanges to splice plates, flange to flange, and web butt <br /> joints are full penetration welds with effective weld throat equal to <br /> L, or exceed'ng the required strength of the joint. <br />
