What’s New & Improvements

​
Engineering Calculators:

  • Masonry Gravity Wall (LRFD) 🇺🇸: NEW! Introduced the first version utilizing TMS 402/602-22 strength design methodology, featuring rectangular stress blocks and dynamic phi factors via strain compatibility.
  • Wind Loads MWFRS (ASCE 7-22) 🇺🇸: Added the complete Directional Procedure with new wind direction inputs, direction-dependent roof angles (θdir\theta_{dir}), and comprehensive pressure coefficient tables.
  • Wind Load Parapets (ASCE 7-22) 🇺🇸: Implemented dedicated pressure calculations for both MWFRS and C&C, including parapet-top exposure calculations.
  • Snow Load Drifts (ASCE 7-22) 🇺🇸: Fixed leeward drift calculations to strictly enforce 8×hc8 \times h_c width limits and prevent drift heights from exceeding available clear height.
  • Steel Composite Beam (LRFD) 🇺🇸: Corrected short-term and long-term deflection logic specifically for cases involving precamber.
  • Steel Bolt Analysis 🇺🇸: Updated technical references to include the AISC Steel Construction Manual 16th Edition.
  • Wall Footing 🇺🇸: Updated template to default to IBC 2024 / ASCE 7-22 standards with revised clause citations.
  • AU/NZ Steel Sections 🇦🇺 🇳🇿: Resolved calculation errors for C350L0-T1 sections caused by string-comparison logic in the template back-end.

Atlas Tube Connection Hub

  • WF-to-HSS Shear 🇺🇸 🇨🇦: The Extended Configuration now supports single vertical bolt rows, single-bolt-per-row options, and user-defined vertical bolt spacing inputs.
  • HSS Round X-Connection 🇺🇸: NEW! Developed comprehensive design for round HSS X-connections including member force interaction and AISC 360-22 limits of applicability.
  • HSS-to-WF OMF Seismic 🇺🇸: Implemented Ordinary Moment Frame seismic limit states with SDC determination and Table 12.2-1 validation.
  • Bolted Splice Shear 🇺🇸: Added comprehensive shear limit-states covering column yielding/rupture and plate block shear. Now enforces a 4x4 bolt grid maximum per AISC 316-22.
  • HSS-to-WF Shear 🇺🇸: Extended end-plate connection support for combined axial and shear demands with new governing load combination tracking.
  • HSS Truss Connections 🇺🇸 🇨🇦: Enhanced UX with a new “General HSS - Truss” preset and improved connection classification displays.
  • Brace-to-Column 🇺🇸: Extended support for HSS beams and columns with new web transverse shear yielding checks.
  • Steel Connection Stiffeners 🇺🇸 🇨🇦: Fixed guidance messages that incorrectly suggested reducing stiffener lengths; logic now correctly recommends increasing length for HSS/WF moment connections.
  • Shuriken Bolt Validation: Corrected workable-flat validation placement from beam to column widgets across all HSS Moment and Splice templates.

​
Calcs Builder

  • Preset Management: Introduced advanced referenceId dependency tracking with migration tools to identify and fix orphaned references.

​
Platform Improvements:

  • Homepage Redesign: Rebuilt the main dashboard with a modern responsive layout, improved project tables, and “Quick Start” shortcuts.
  • Project Sidebar: De-restricted visibility of the “Calculation Upgrades” link, allowing users to move templates to newer code editions more easily.
