To verify the functionality of the non-linear diagram spring elements with P-Delta and Large Displacement theory effects, when simulating a non-linear analysis contact problem.
A continuous beam with 20m long is supported by non-linear diagram spring elements and loaded by one concentrated force of 75 kN at one of the extremes and by its self-weight G.
The concentrated force is successively incremented from 75kN to 150kN.
The non-linear diagram spring properties are the following ones:
Forces and displacements obtained are presented below:
