HI
I AM FACING FEW PROBLEM WHILE ANALYSING REBOILER PIPING

1)IF REBOILER SUPPORT IS HARD SUPPORT THEN IT WILL BE HOLD DOWN OR SIMPLE REST SUPPORT ? HOW TO AVOID UNBALANCED BETWEEN FOUR LUGS DUE PIPING EFFECTS.IT INCREASES NOZZLE LOADS ALSO IF HOLD DOWN SUPPORT.

2)ONE OF COLUMN IS HANGED(PLACED)BY LUGS ON STRUCTURE AND REBOLIER N PIPING IS BELOW THAT STRUCTURE, DUE TO THIS DISPLACEMENT ARE HIGH N NOZZLE LOADS INCRESRES DRASTICALLY EVEN PLACING THE SPRINGS(REBOILER PIPING IS STIFF N NOT POSSIBEL TO REROUT), HOW TO OVERCOME THIS PROBLEM?
