Use this option to determine if the old spring can still be used. If the old spring can be used, then the new preset (initial cold load) is determined. If the old spring cannot be used, then a new spring design is recommended. The old spring is always left in the problem for subsequent load case analysis. The old hanger information needed for the redesign is:

  • The hanger table

  • The number of springs at the location

  • The old spring rate

The old spring rate is entered in the Spring Rate box under Predefined Hanger Data. The Theoretical Cold (Installation) Load must not be specified.

Three springs at node 97. Each have a
spring rate of 1105 pounds/inch.
