  • Restrained Retaining Wall 🇺🇸: Released IBC 2024 and ASCE 7-22 version with improved shear key widget visibility.
  • Wind Load Templates 🇺🇸: Added parapet calculations for ASCE 7-16, fixed MWFRS Exposure B KhK_h minimum for low roofs, and implemented BFS 2024 wind maps.

🛠️ Improvements & Fixes

  • Snow Load ASCE 7-22 🇺🇸: Updated drift height formulas, replacing ww with respective roof lengths for leeward and windward calculations.
  • Timber Connectors ASD 🇺🇸: Updated Simpson Strong-Tie connection database based on the 2026-2027 catalogue.
  • Concrete Column 🇺🇸: Added X/Y axis compass annotations to section view diagrams for improved orientation clarity.
  • Composite Beam LRFD 🇺🇸: Fixed stud spacing calculations to properly constrain layout and added utilization reporting for shear strength.
  • Masonry Wall ASD 🇺🇸: Fixed self-weight calculations for fully grouted walls by correcting section properties.
  • Steel Beam 🇨🇦: Added minimum width and depth filters to the member selector.
  • Wood Beam Templates 🇨🇦: Optimized the one-page summary for letter size by hiding non-essential widgets.
  • Timber ITI Database 🇨🇦: Fixed and reorganized the internal database structure.
  • CFS Steel Member 🇦🇺: Corrected M1/M2M_1/M_2 references for unequal end moment coefficient calculations per AS4600.

Atlas Tube Connection Hub

🚀 New Features

  • WF-to-HSS Shear Connection 🇺🇸: Added missing limit states including block shear, strength at bolt holes, and plate buckling for Single and Through Plate connections when axial loads are present.
  • HSS-to-HSS Round X Connection 🇺🇸: Implemented complete limit states for TKYX shear calculator with summary diagrams and valid cases for both gapped and overlapped configurations.
  • WF-to-HSS Moment Connection 🇺🇸: Added OMF seismic limit state checks per AISC 341, including joint capacity evaluation for wrap-around/diaphragm cases with beams on both sides.
  • Column Bracing 🇺🇸: Added forked end plate calculations including cap plate capacity, HSS face local yielding/crippling, splice-to-cap plate weld checks, and introduced initial support for the “Bolted Knife Plate” brace connection option.
  • HSS-to-HSS Shear Connection 🇺🇸: Implemented comprehensive axial load limit states for Exterior Plates, Coped Beam, Thru-Bolt, Single Plate, and Field-Welded connections.
  • HSS-to-WF Shear Connection 🇺🇸: Expanded the End Plate/Face Plate calculator with tension and compression limit states across beam, end plate, bolts, face plate, and WF column components.
  • Truss Type Connection 🇺🇸: Added 19 new validation presets for combined connections (K&Y, K&X, X&Y, X&T, Y&Y, Y&T variants) and refined load distribution logic for K-type connections.
  • HSS-to-HSS Shear Connection 🇨🇦: Added axial load limit states for Single Plate, Coped Beam, External Plates, and Through Bolt Coped Beam connections.

🛠️ Improvements & Fixes

  • Dynamic Diagrams 🇺🇸🇨🇦: Updated Column Bracing and Chevron Bracing calculators to support HSS sections with generalized geometry equations.
  • HSS-to-HSS Shear Connection 🇺🇸: Enhanced dynamic diagrams with weld symbols, extended side view configurations, and top view for through-bolt and coped beam connections.
  • WF-to-HSS Moment WT Connection 🇨🇦: Added top view visualization and fixed weld symbol display for Short Tee configurations.

Platform Improvements

🛠️ Improvements & Fixes
