Situation 1:
A light crane rail sits on and is securely fastened
to a W crane girder. The girder is simply supported
on a span of 6 m. The crane wheel loads are as
follows: V= 80 kN and H = 8 kN. Assume full transfer
of lateral load to the top flange of the girder.
Girder properties:
Weight = 67 kg/m
Sx = 1, 280 x 103 mm3
Sy = 361 x 103 mm3
Allowable stresses:
Fbx = 164 MPa
Fby = 186 MPa
Determine the actual bending stress
about the x- axis.
