What’s New & Improvements
Engineering Calculators:
- Wind Load Overhangs (ASCE 7-16/22) 🇺🇸: Added comprehensive support for roof overhangs with new coefficient tables, pressure calculations, and conditional UI for MWFRS and C&C.
- Wind C&C Individual Areas (ASCE 7-22) 🇺🇸: Introduced the ability to define specific effective wind areas for individual zones with per-zone coefficient tables and pressure plotting.
- Masonry Shear Wall 🇺🇸: Now allows 8-inch vertical bar spacing with integrated grouting validation.
- Wood Templates (NDS 2024) 🇺🇸: Updated all US wood calculators—including Timber Beams, Columns, Members, Roof Ties, and Shear Walls—to align with IBC 2024 and AWC NDS 2024 standards.
- Masonry Gravity Wall (ASD) 🇺🇸: Updated to TMS 402/602-22 with improved CMU geometry calculations and revised section properties per CMU-TEC-002-23.
- Timber Beam 🇦🇺: Added a custom species option allowing users to define unique material properties and strength values.
- ASCE 7-16 Hip Roofs 🇺🇸: Fixed minimum negative coefficient calculations for zone 2e to consistently utilize h/l ratios.
Atlas Tube Connection Hub
- Steel Connection Axial Loads 🇺🇸 🇨🇦: Implemented axial load inputs and limit states for HSS-to-HSS and WF-to-HSS connections, including combined demand calculations.
- WF-to-HSS Shear Connections 🇺🇸: Added dynamic top-view diagrams with weld symbols for single-angle, double-angle, and WT connections, including geometric checks for built-up tees.
- HSS Truss Type Connections 🇺🇸 🇨🇦: Implemented comprehensive limit states including chord punching shear, branch local yielding, chord sidewall shear, and weld checks.
- WF-to-HSS Shear (CSA S16) 🇨🇦: Added full axial load support (tension/compression) and plate limit states including tensile yielding, rupture, and block shear.
- HSS-to-HSS Shear (CSA S16) 🇨🇦: Implemented “Extended Configuration” for single plate, coped beam, and through-bolt connections with new block shear and eccentricity analysis.
- HSS Splice Connections 🇺🇸 🇨🇦: Added shear limit states for interior and exterior connections with directional shear toggles and slip resistance checks for slip-critical options.
- Chevron & Column Bracing (CSA S16) 🇨🇦: Added internal force inputs and HSS-specific capacity checks with stress interaction factors.
- Atlas Tube OMF Checks 🇺🇸: Added Seismic Force Resisting System (SFRS) validation with ASCE 7-22 shared tables and height/permission checks in Project Defaults.
Calcs Builder
- Rich Text Review Comments: Enabled rich text editing in the publish review modal for improved formatting and clearer feedback.
- Widget Visibility Improvements: Enhanced drag-and-drop behavior with clearer visual indicators for sections containing hidden widgets.
- Review Mode Usability: Made default value fields scrollable to ensure long input strings remain fully visible during review.
- Admin Template Upload: Extended fast JSON import improvements to admin pages via a new feature gate for faster management.
Platform Improvements:
- Timber Column “Supersummary”: Streamlined the display by hiding redundant constants (capacity/system factors) while keeping critical dynamic values visible.
- Project Defaults (IRC 2015): Resolved an “unexpected error” by fixing the conditional rendering of the wind speed GIS widget for the 2015 IRC edition.
- Summary View Enhancements: Added key calculation widgets to the summary view for ICC Allowable Area and Occupant Load templates to improve scannability.
- Organization: Moved the Live Load Pattern widget to the “Loads - Composite” section in the Steel Composite Beam calculator for better workflow logic.
