A membrane is stretched using isotropic prestress between two radii of two concentric cylinders not lying in a plane parallel to the vertical axis. Find the final minimal shape of the membrane - the so-called helicoid, and determine the surface area of the resulting membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in analytical solution, also self-weight is neglected in this example.

In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
Using the "Base Plate" component, you can design base plate connections with cast-in anchors. In addition to plates and welds, the design analyzes the anchorage and the steel-concrete interaction.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
