Structural Analysis Software

Development of Structural Analysis Software

For an optimized structural/geometrical analysis and design, the folling Windows programs have been developed amongst others:

RAHMEN: Software program for general three-dimensional structural systems with truss-, beam-, and cable-elements, developed for the form-finding process for lightweight structures and structural analyses according to 2nd order theory with large deformations. The following special functions are available:

- Form-finding elements taking into account the prestress level as well as the elastic stiffness of regular structural elements
- Cable element (various types, adaptive cables like tensioning element or fitting element, non-linear material)
- Compression strut (compression only, bearing- or spring-element, also with displacement presetting)
- Beam Element (15 types, also with normal-force-exclusion or torsional hinge)
- Elastically bedded beam element
- Generation of load surfaces
- Application of prestress and deadload precambering
- Discrete load stages for determination of buckling- and failure-loads
- Control of bandwidth optimization for acceleration of solution of the stiffness matrix equation
- Frequency calculation according to the energy method (Rayleigh-method)
- Data exchange with AutoCAD via DXF-files (geometry, structural elements, analysis results)

GEONET: Program for geodetic analyses of lines and surfaces as well as for flat projections and cutting patterns of surfaces, application for geometry optimization and patterning of cable-nets, membranes, and domes

VSTUETZE: Design of composite columns according to DIN 18806-1, DIN 18800-5 und EN 1994 (Eurocode 4) including structural fire design according calculation method or tabulated rules

VTRAEGER: Design of composite beams according to EN 1994 (Eurocode 4) including structural fire design according to calculation method or tabulated rules

DLTRAEGER: Program for structural analysis of multi-span continuous beams
