@le99, I'm sorry for not providing a clear picture at the beginning as I was rushing the stiffness to piping.
@PMR06, I got your point. I was doing the conservative approach as well. We got requests from two groups. One is asking support stiffness for piping stress, the other is for boundary...
Thanks folks for your replies. The issue is exactly As PMR06 mentioned that piping stress engineer was requesting the support stiffness at each support point for Caesar analysis. All the T-post type supports are welded on top of a common steel skid (lateral rigid) which is welded on top of 10...
Unfortunately the support stiffness obtained from first method is approx. the number of supports x the stiffness obtained from second method when the loads and supports are same and all supports share one rigid common piling/foundation system.
I'm wondering which method is theoretically...
Thank you @le99 for the reply. I'm wondering which method is correct in theory. The system has been modelled in Staad. The first method is to apply only one load on one support to calculate the support's stiffness. The second method is to apply all loads on all supports to calculate the...
Hello folks,
Currently I got a task to obtain the equivalent lateral stiffness of one support in a steel skid supporting piping system. These are 25 supports on the structure at different elevations - some are T-post and some are frames. The common steel skid is supported on 10 piles. It has...
