What’s New & Improvements
Engineering Calculators
🚀 New Features- Steel Composite Beam (LRFD) 🇺🇸: BETA — Released a new calculator aligned with AISC 360-22 for the design of beams acting compositely with concrete slabs.
- Supports composite/precomposite bending strength and plastic/elastic neutral axis determination.
- Includes shear connector design, construction-stage checks (shored/unshored), and serviceability analysis for deflections and stiffness.
- Handles metal deck or solid slabs, various deck orientations, and continuous beams.
- AISC 360-22 Updates 🇺🇸: Upgraded Steel Beams and Steel Base Plate templates to the latest standard.
- Project Defaults 🇺🇸: Added automatic wind and tornado speed determination for ASCE 7-22 using new contour databases.
- Snow Loads (ASCE 7-22) 🇺🇸: Enabled API output capabilities for key results, including design pressures and drift calculations.
- General Beam Analysis 🇺🇸: Added a load direction selector across beam calculators, allowing users to specify axial () or lateral () load transfer modes.
- Project Defaults 🇨🇦: Corrected strength load combinations for uplifting live and earthquake loads in Canadian templates.
- Wood Shear Wall (ASD) 🇺🇸: Corrected Footnote 2 application to apply only to unblocked walls per SDPWS standards and fixed sheathing logic.
- Foundation Pier Footing 🇺🇸: Fixed self-weight consideration logic for downward and uplift capacity calculations to ensure consistency when self-weight is excluded.
Atlas Tube Connection Hub
🚀 New Features- Built-Up Tee Support 🇨🇦: Added built-up tee section options for HSS-to-HSS and WF-to-HSS moment connections, featuring new geometry inputs and weld calculations.
- Column Bracing 🇨🇦: Added a Bolted Connection preset, new single plate capacity sections, and comprehensive CSA S16:19 gusset plate checks (yielding, block shear, and interaction).
- HSS Splices 🇺🇸 🇨🇦: Introduced configurable bolt spacing inputs, replacing fixed spacing with user-controlled horizontal and vertical parameters that dynamically update diagrams.
- WF-to-HSS Moment Connections 🇺🇸 🇨🇦: Introduced direct factored load input options, new Shuriken bolt sizes, and effective width corrections for field-welded connections.
- HSS-to-HSS Moment Connections 🇺🇸 🇨🇦: Implemented member-end distance reduction logic (AISC 360-22 / CSA S16:19), applying capacity reductions when connections are near member ends.
- 🇺🇸: Fixed weld directional strength factor () from 1.0 to 1.5 for seated, fin plate, and field-welded connections.
- WF-to-HSS Moment Connections 🇨🇦: Added tension/compression load differentiation, splitting axial demands into separate components with specific bolt demand calculations.
- HSS Trusses 🇺🇸: Enhanced truss connection logic to correctly classify two-branch members with external loads and three-branch member configurations.
Calcs Builder
🚀 New Features- Review Mode:
- Introduced character-level highlighting in equation inputs, making it easier to spot specific modifications within long expressions.
- Enabled granular widget merging when sections are added or removed and allowed commenting on removed widgets.
