Software TRUSSES+ version 1.0
De nieuwe TRUSSES+ software (ArcelorMittal) is bestemd voor het voorontwerpen van vakwerken met grote overspanning conform de Europese normen (EN1993-1-1:2005) voor staalstructuren. De software kan ook worden gebruikt voor controle en om structuren te optimaliseren.
The software can be used as an automatic pre-design tool.
- Verification: based on sections imposed by the user, TRUSSES+ checks the design criteria of each member of a truss (upper and lower chords, bracings)
- Optimization: from basic data supplied by the user (main geometry, lateral restraints and loadings), the software estimates the dimensions of the cross-section of elements of the structure
The field of application of TRUSSES+ is:
- 2 dimensional truss model, simply supported, with user defined positions of lateral restraints
- Truss configurations:
- Geometrical limits:
- Length = min: 5m, max: 100m
- Height = min: 0.2m, max: 10m
- Height/Length ratio = min 1/30, max: 1/10
- Program sales of ArcelorMittal for I, H, double L, and U-sections
- Steel grades and standards : EN 10025-2 & 4, EN 1993-1-1, HISTAR S355&S460
- Multiple loading cases with definitions of:
- Distributed loads: Permanent, Imposed, Wind and Snow loads
- Concentrated loads: Permanent and Imposed loads
The calculations performed are:
- Automatic load combination of the elementary load cases for Ultimate Limit States (ULS) and Servicability Limit States (SLS)
- Classification of sections
- Verification of cross-section resistance
- Verfication of the member stability: flexural buckling in-plane and out-of plane
- Verification of deflection limits and estimation of natural frequencies (SLS)
... According to Eurocodes
The results are provided as:
- vizualisation on the software interface
- 3 levels of details of Preliminary Design Notes, with:
- Data of the truss and calculation parameters
- Analysis results (reaction at supports, node displacements, internal forces)
- Verification results (ULS and SLS)
- Data of the truss and calculation parameters
