Impacts of an earthquake on hangers
Impacts of an earthquake on hangers
(OP)
I currently study seismic effects apply to a piping structure with spring hangers. I would like to know, what are impacts of an earthquake on these spring hangers. Here are my questions:
1) What are, in "hanger report W/ Text", "vertical movement" and "horizontal movement"?
2) Do these values vary according to loads applied to the structure studied like uniform load?
3) In "hanger report W/Text", "maximum table displacement range" concerns the maximum displacement vertical? Horizontal? Or both?
4) What are, in "hanger report W/ Text", "minimum allowed single spring load" and the "maximum allowed single spring load"?
5) How can I know if hangers will stand up to the seismic load? Is it just to compare the displacement at the node connecting piping and hanger with "max table displacement range"?
Regards

2) Yes.
3) Vertical, and this is the maximum value from the table as a while, not for that one spring.
4) The load limits for that spring - from the hanger table.
5) Yes.

I would like just a detail about question 5):
For the node where there is the hanger, the comparison is well possible between "Displacements" in "standard reports" and "max table displacement range" in "hanger report W/ Text"?

The maximum table displacement is the largest travel value from the entire table.

In fact, I don't understand well the difference between the two... Normally, she should be the same value, no?
