## Spring with friction modelling in caesar II - 11/12/19 04:08 AM

Dear experts,

I am working on reboiler-column stress analysis

during analysis, I found the requirement of spring support and modelled the same as per standard practice in caesar.

Nozzle loads on reboiler and column nozzles drop down drastically when modelling of spring.

here reboiler is supported from the column.

one question comes that what about the friction effect especially spring is design for huge vertical loads from reboiler

hence I decided to model spring support with friction.

can somebody guide me the procedure for modelling of spring support with friction when the connection to column(C-node is already been utilized for column connection)?

Thanks in advance for your help

note that spring is provided due to temperature difference between column and reboiler even though support is from column
