Bearing capacity of hollow tube
Hi,
I'm trying to find the capacity of a hollow tube / pin which is subjected to transverse loading. The pin is inserted in to a trestle and two trestles are used to support a beam. My knowledge is limited to basic calculations with simple beams and when I've tried applying what I know, the figures don't seem to be correct. So, as an example, if we take a hollow tubular section of steel that is simply supported at each end and apply a transverse UDL to it, we get a maximum shear force, maximum bending moment and deflection. How do I use these figures to determine if the section will support the force applied to it?
Let's say we have a 1 m length hollow tubular section of 100 mm diameter and wall thickness of 10 mm. The UDL is applied across 0.8 m of the length of the section from the centre (i.e. a gap of 100 mm each side). Let's say the steel grade is 350 N/mm2. What is the maximum load the section can elastically support?
Many thanks in adavance
