Spring Support on structure

asked in General Forum by (120 points)

Hello everyone.

I need to create a structure similar to the one shown below, containing multiple loads and supports. One of these supports happens to be a fixed spring (in red) with a known stiffness of 80 kN/m. However, I have absolutely no idea how to create this kind of constraint. How can I define a spring support such as this one, so that the displacement in node A will be equal to the force applied to the node divided by the spring stiffness ( x=F/k) ?

Thank you in advance.
