Holding Down Bolt Design Method
Holding Down Bolt Design Method
(OP)
Hi,
I am involved in the design of a pressure vessel which has an unpressurised skirt at its base, and is subjected to overturning moments such that the vessel/skirt has a set of holding down bolts. (PCD circa 6000mm).
We currently use methods by Dennis R Moss in " Pressure Vessel Design Manual" but we are looking for an alternative to this procedure.
Any sugestions or examples of other methods for designing these? I am looking for designs for Individual chairs, chairs with compression rings, single and double gussets etc.
thanks in advance.

RE: Holding Down Bolt Design Method
interest to you for this application?
I assume your axis is vertical.
Have not seen the model that is used
in Pressure Vessel Design Manual so
I am not certain if they are the same
or different. I know that the bearing
bolting technology takes into consideration
of combined loading ie axial, moment, and
radial.

We use two methods, an "equivalent area" method and an eccentric load method.
