Springs

• Springs represents two two-noded members with stiffness parameter, usually used while modeling bearings in bridges.

Open

• Difference between Line and Spring objects is that, Line objects gather their stiffness values from their section parameters while springs' stiffness parameter can be modified by user.

• From model below we can see the behavior difference between same structure modeled with lines and springs.

Stiffness Parameter

• Click ⋮ icon next to the desired stiffness parameter input cell.

• User can either choose between Free - Fixed options or select Edit Stiffness option.

• In Edit Link Stiffness tab user can manipulate stiffness value to match desired behavior.
