Structural Analysis and Design for Shipbuilding and Floating Bodies

Structural Engineering Software for Shipbuilding and Floating Bodies

The structural engineering programs RFEM and RSTAB are suited very well for structural analysis of ships or ship components (for example ship cranes, masts, hulls, pulleys). It is also possible to consider nonlinearities such as cables and to perform dynamic, stability, and buckling analyses. Moreover, it is possible to model and design shipping containers in RFEM.

Furthermore, it is possible to design floating bodies, such as pontoons, floating jetties, inflatable islands, special rafts, floating houses, houseboats, dredgers, floating cranes, et cetera.

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. 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 & Design of Frame/Beam/Truss Structures

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

Wind Simulation & Wind Load Generation

Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Reconstruction of Sailing Ship 'Alexander von Humboldt II', Germany

RFEM Model of Sailing Ship 'Alexander von Humboldt II'

The sailing ship 'Alexander von Humboldt II' began its service in October 2011 and has been conquering the seas ever since.

The ship, operated by German Sail Training Foundation (DSST), is a barque rigged with three masts. The masts and the hull consist of steel.

In addition to typical FE calculations of highly stressed systems such as mooring, anchor and davit units, the rigging forces were analyzed in detail.

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.

Calculation of stiffened buckling panels according to EN 1993-1-5, 4.5

In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5. The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
