Loads caused by earthquake to Skids
Loads caused by earthquake to Skids
(OP)
Gentlemen (Ladies)
Well here's the problem; I have some skids, no big stuff, no HiSci or anything, just som skids/ cabinets,with some pipes/ tubing. Now they want to know if the equipment is useable or repairable after an earthquake.
The peak Acceleration occurs after 0,2 sec.
Mean Spectral Acceleration Horizontal; 1,81 (g).
Mean Spectral Acceleration Vertical ; 1,29 (g).'
Is it possible to get a usable evaluation to this problem by just adding these (peak) acceleration forces to the leg's connection points?
I use SolidWorks and CosmosWorks (premium package, this do not have the CosmosWorks module that handles this problem).
Any (easy) ideas will be appreciated..
Regards

And when you do the problem, constrain the feet or bottom as it normally would be constrained and direct the g force at the center of mass of the structure.
As a final remark, I doubt that there is a structural problem with a skid due to an earthquake.
Buildings, on the other hand, are subject to damage due to the horizontal forces , which though modest in terms of g forces, are loading a significantly weaker structure than your skids.

Before getting jumped on in this forum, recognize this is simply a very idealistic way to get a number. It would be a starting point for your analysis.
