How to design and calculate ear-type support bolts
Thread Content
What is the function of the non-standard ear-type support bolts, and are they subjected to stress? What kind of force is acting on it?

When stress is applied, it consists of lateral shear forces and tensile or compressive forces resulting from bending resistance in the vertical direction; the compressive forces can be ignored, and only the tensile forces need to be considered. Sometimes it is necessary to check the bending resistance of the ear bracket’s base plate or even its reinforcement plates. This is done by estimating the external loads acting on the pipe, such as those caused by wind and earthquakes
Take a look at \"Chemical Process Equipment Design Series\" – the chapter on \"Chemical Vessels\" – and you’ll understand.
It seems the new version of the pressure vessel design guidelines contains relevant instructions. . .
The bolts are under tension to prevent the equipment from toppling over
\"Series on Chemical Equipment Design\": Chemical Vessels, Chapter 8: Support Design – it contains relatively detailed calculations
