	NOTATION
	a	length, plate, parallel to force
	b	width, plate, normal to force
	R	radius, cylinder
	t	thickness, plate
	P	force
	Mo	Moment, about cyl centre
	Py	force, max line

APPLICATION

Cylinder fixed to two flat plates normal to the cylinder axis and subject to a transverse moment. This detail has been identified on the slewing column of jib cranes, forming the connection between the slew-ring cylinder and the slewing platform, supporting the jib heel and A-frame.

OUTPUT

Weld shear stress fixing cylinders to plates & in-plane stresses in plates

THEORY

refs

GUIDANCE

While the loading state is the most elegant possible, need further experience of application and FE results to build confidence of accuracy. Presently evaluated as conservative.
