In configur/computation control,Hanger Default Restraint Stiffness default value is 1e12.I don't know what is 'Hanger Default Restraint Stiffness'.If it is 50,000,what will happen?

This setting permits you to have a "default restrained weight" stiffness that differs from the "default translational" stiffness. Note that the "restrained weight stiffness" is only used during hanger design, in the Restrained Weight load case.

Typically the CAESAR II default value is sufficient, and you don't need to adjust this. The only time I've ever had to fool with this setting is when we've had to benchmark (match) results from another program (that used a different value).

thanks!
