🎉 Ending 2025 — This release marks the final updates of 2025!
What’s New & Improvements
Engineering Calculators:
- Seismic Analysis 🇺🇸: Added SFRS Class H support for steel systems not specifically detailed for seismic resistance.
- Project Defaults 🇺🇸: Introduced CBC 2025 support, aligning project load standards with ASCE 7-22 and IBC 2024.
Atlas Tube Connection Hub
- Direct Factored Loads 🇺🇸 🇨🇦: Expanded direct factored load input capabilities across HSS-to-HSS Splice, Chevron Bracing, Base Plate, and Truss connections. Users can now toggle between individual load inputs and direct factored loads with updated conditional visibility and load combination logic.
- HSS-to-WF Moment Connections 🇺🇸 🇨🇦: Added comprehensive axial load handling with new connection axial load inputs, factored load combinations (ASD/LRFD/LSD), and axial demand widgets for both positive and negative moment scenarios.
- HSS Concrete Filled Moment Connections 🇺🇸 🇨🇦: Introduced beam axial load tables with combined axial-moment checks and added governing limit state percentages to the top header for quick reference.
- HSS Trusses 🇺🇸: Expanded two-branch support to include TKYX connection classification, load distribution tables, and comprehensive geometry and section property inputs.
- WF-to-HSS Shear WT Connections 🇺🇸: Added built-up tee capability with new input widgets, conditional logic, and dynamic summary diagrams that include flare bevel welds.
- WF-to-HSS Moment Connections 🇨🇦: Added support for the Diaphragm II connection type, including new limit states, bolt/weld calculations, and shear flow modifications.
- HSS-to-HSS Moment Connections 🇨🇦: Enhanced analysis to handle simultaneous positive and negative moments with separate top and bottom limit state evaluations.
