TEDDS occupies a critical niche in structural analysis. It automates the tedious, error-prone process of hand calculations while maintaining complete transparency and code compliance. For routine component design, load takedown, and verification of FEA outputs, TEDDS increases productivity and reduces risk. However, it should be viewed as a complementary tool to global analysis software, not a replacement. The ideal workflow involves global FEA for overall behavior, TEDDS for detailed member and connection design, and BIM integration (Tekla Structures) for modeling and detailing.
Unlike spreadsheet-based tools (Excel), TEDDS calculations are not just numeric outputs. Each calculation is a dynamic, editable description. When an input changes (e.g., span length, load magnitude), the entire calculation and the resulting text report update instantly. This ensures traceability—every number in the final report originates from a formula or code clause. tedds structural analysis
Structural analysis is traditionally bifurcated into two phases: global analysis (determining internal forces, moments, and deflections) and component design/checking (ensuring individual members and connections have adequate capacity). TEDDS excels in the latter while offering robust tools for the former, specifically for simpler structures like beams, columns, slabs, and foundations. Developed by Tekla (a Trimble company), TEDDS allows engineers to create calculation sheets that automatically apply relevant building codes (Eurocodes, ACI, AISC, BS, etc.).
