Modeling in RFEM
During the modeling, you have to enter the cable as a continuous polyline with at least three nodes. Thus, the program "knows" that the entire cable is an element. Then, you can assign the "Cable on Pulleys" member type to this polyline. At least one end of the cable member must have a fixed support or a member, so that the applied tensile load can be transferred. Since the tensile force should be constant in the "cable on pulley", no further definition is necessary for the connected elements. The adjacent elements or nodal supports receive deflection forces if there is buckling on the cables.
When modeling, rigid members were applied in such a way that the slab force can be displayed on a support. Additional stabilizing supports were arranged on the loose pulleys to counteract the instability.
The required pulling distance was applied by means of an imposed nodal deformation.
