Engineering Calculators

​
🚀 New Features

  • 🚧 NEW CALCULATOR COMING SOON Combined Footing (IBC 2024) 🇺🇸: Introduced a new prototype calculator based on the spread footing template, featuring comprehensive load inputs, outputs, validation cases, and shear, moment, and applied load diagrams based on governing load combinations with refined beam analysis outputs.
  • Spread Footing (IBC 2024) 🇺🇸: Added uniaxial column offset support with dynamic diagrams and bounds checking to prevent columns from being placed outside the footing plan area.
  • Masonry Shear Wall LRFD 🇺🇸: Implemented Segmented Method Analysis for walls with openings, including pier rigidity calculations and proportional base shear distribution.

​
🛠️ Improvements & Fixes

  • Steel Composite Beam LRFD 🇺🇸: Added a variable stud spacing table for different arrangements along beam spans with a new span-based design summary and nominal shear strength calculations. Clarified stud anchor terminology (rows vs. individual studs) and improved longitudinal spacing validation for perpendicular deck orientations.
  • CFS Steel Beam (AISI) 🇺🇸: Improved combined bending/shear and bending/web-crippling summary results with clearer interaction vs. utilization reporting and expanded interior support options for built-up beams.
  • Timber Shear Wall ASD 🇺🇸: Corrected floating-point precision errors in member schedule designations and resolved holdown reference errors when holdown design is disabled.
  • Wind Load C&C (ASCE 7) 🇺🇸: Updated comments field synchronization for Member Schedule page integration.
  • NeXTimber GL13 Sections 🇦🇺: Added comprehensive glue-laminated timber sections to the member selector via the timber_v2 shared table (Australian timber design), with full geometric and material properties.

Atlas Tube Connection Hub

​
🚀 New Features

  • Bolted Truss Connection (AISC 360-22) 🇺🇸: Introduced a new stepped tube bolted truss connection calculator with comprehensive limit states covering bolts, gussets, chord and branch members, and welds, including applicability limits and summary outputs.
  • HSS Truss Connection (AISC 360-22) 🇺🇸: Added validation cases for Fig. 9-3 connection classification examples (d), (e), and (f), plus comprehensive test coverage for combined connection types (K&Y, K&X, X&Y, X&T, Y&T, Y&Y) with round/square and gap/overlap variants.
  • Overlapped Round KT Connection 🇺🇸: Implemented TKYX shear calculator for overlapped round KT connections with AISC 360-22 Section K3 applicability checks and Table K3.2 limit states.
  • HSS Column Splice — Field-Welded External (AISC 360-22) 🇺🇸: Implemented shear limit states for Field-Welded External connections, including HSS capacity, plate capacity, and weld capacity sections with combined axial and shear interaction checks.
  • Column Splice PJP Shear 🇺🇸: Added HSS limit states for shear yielding, shear rupture, and interaction checks, plus updated weld capacity calculations incorporating shear stress effects.
  • WF-to-HSS Moment Connection 🇺🇸: Extended Flange Plate and WT connections to support beams on two sides of HSS columns with corresponding limit states and factored column moment inputs.
  • HSS-to-HSS Moment Connection 🇺🇸: Added OMF seismic limit state checks with project defaults integration, vertical seismic load inputs, and enhanced load combination handling.
  • Concrete-Filled HSS Column 🇺🇸: Introduced one-side beam location support, separating load inputs and computational logic for single vs. dual beam configurations.
  • Column Brace — Knife Plate 🇺🇸: Added bolt tension and combined tension-plus-shear interaction checks, corrected the block shear equation, and adjusted buckling length for forked conditions.
  • HSS-to-WF Shear Connection 🇨🇦: Added beta axial load support with new tension and compression limit states across beam, end plate, bolts, face plate, and WF column components, plus combined loading interaction checks.
  • WF-to-HSS Shear WT Connection 🇺🇸: Implemented axial load capabilities with new demand inputs and capacity checks, correcting bolt hole strength reporting in summary outputs.
  • WF-to-HSS Shear WT Connection 🇨🇦: Added axial load calculations for WT connections including new limit states for beam, column, and bolts with corrected phi factors.
  • HSS-to-WF Shear Connection (CSA S16:19) 🇨🇦: Added CSA S16:19 fillet-weld group factors for axial load cases with a new MwM_w reduction factor and orientation-based strength enhancements.

​
🛠️ Improvements & Fixes

  • Dynamic Diagrams 🇺🇸: Added top-view diagrams for External Plates, Coped Beam, Unstiffened Seated, and Wrap-Around connections with Shuriken hardware visualization. Updated the overlapped round KT connection diagram with new geometry parameters.
  • Column Bracing — Forked End Plate 🇺🇸: Implemented dynamic diagram support for bolted forked end plate connections, including double-shear knife plate configurations.

Platform Improvements

​
🛠️ Improvements & Fixes

  • Organization Landing: Users are now taken directly to the home dashboard after logging in, rather than landing on an intermediate page.
  • Image Widget Labels: The label field for image widgets in the Builder has been restored, and now shows a thumbnail preview so you can identify the right image at a glance.
  • Preset Editing: Corrected an issue where preset changes would occasionally fail to save, so your settings and values are now reliably stored every time.
