Shear onnectors
Steel stud shear conn shall conform to the requirements of Structural
Welding Code-Steel, D1.l.
Manufacturer's certification shall constitute sufficient evidence of conformity
with the code.
The nominal loads shall be the minimum design loads stipulated by the applica-
ble code under which the structure is designed or dictated by the conditions in-
volved. In the absence of a code, the loads and load combinations shall be
those stipulated in the American National Standard inimum Design Loads
for Buildings and Other Structures, ANSI A58.1.
The dead load to be assumed in design shall consist of the weight of steelwork
and all material permanently fastened thereto or supported thereby.
The live load, including snow load if any, shall be that stipulated by the appli-
cable code under which the structure is being designed or that dictated by the
conditions involved. Snow load shall be considered as applied either to the en-
tire roof area or to a part of the roof area, and any probable arrangement of
loads resulting in the highest stresses in the supporting members shall be used
in the design.
For structures carrying live loads* which induce impact, the assumed live load
shall be increased sufficiently to provide for same.
If not otherwise specified, the increase shall be not less than:
For supports of elevators 100
For cab-operated traveling crane support girders and their con-
nections
25
For pendant-operated traveling crane support girders and their
connections 10
For supports of light machinery, shaft or motor driven 20
For supports of reciprocating machinery or power driven units 50
For hangers supporting oors and balconies 33
e lateral force on crane runways to provide for the effect of moving crane
trolleys shall be not less than 20 of the sum of weights of the lifted load and
of the crane trolley, but exchive of other parts of the crane. The force shall
*Live loads on crane support girders shall be taken as the maximum crane wheel loads .
