Structural Analysis and Design for Shipbuilding and Floating Bodies

FEM Analysis and Design of Structures

The RFEM program is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Analysis and Design of Beam Structures

The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM, with special attention to beam or frame structures. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.

    Modeling and Calculating a Floating Body with RFEM

    To correctly model and calculate floating bodies (special rafts, pontoons, floating jetties, dredgers, floating houses, inflatable islands, floating cranes, houseboats, et cetera), a two-stage calculation is necessary.

  2. 1 - General Data

    Form-Finding in RFEM

    The RF-FORM-FINDING add‑on module determines equilibrium shapes of membrane and cable elements in RFEM. In this calculation process, the program searches for such a geometric position in which the surface stress/prestress of membranes and cables is in equilibrium with natural and geometric boundary conditions. This process is called form‑finding (hereinafter referred to as FF).

  3. Figure 01 - Cable on Pulleys

    Cable on Pulleys

    In RFEM, you have the option to create and analyze cables using sheaves. For this, use the ‘Cable on Pulleys’ member type. It is ideal for pulley systems, where the longitudinal forces are transferred via sheaves.
