Bridge Design


Bridge design is one of the most complex and fascinating disciplines of civil and structural engineering. The extensive and powerful group of programms offered by SOFiSTiK is available to analyze and design a wast amount of bridge types. Besides the evidently implemented DIN-Fachberichte 101, 102 through 104, many other international codes such as EC, SIA, Ö-Norm, BS, EHE, SNIP, IR or ACI can be selected.

3D FEM ultimate

3D Industrial Design and Bridge Design

The 3D FEM ultimate package provides all the tools for modern structural analysis in civil engineering and bridge design. In addition to the graphical input capability by the AutoCAD® add-on SOFiPLUS, the parametric axis - related graphical modeling CABD or the Master-cross section which allows any cross sectional profile, can be used. The usage of Pre- and post-tensioned beam- and shell-elements, along with the ULS and SLS design and stress checks offer the capability of project analysis of prestressed concrete and composite systems. Full geometrically nonlinear analysis (Theory of 3rd order) gives the possibility for cable and shell buckling calculations. Traffic load calculation with influence line method and a large library of road and railway loads, is also available to the user. High-end SOFiSTiK technologies such as DYNA for dynamic analysis and HASE for semi-infinite solid simulation can be added optionally.
