Features
34 connection types and calculators, grouped as in the app's new-connection wizard. Each one checks strength and detailing to AISC 360-22, draws itself to scale, and writes its own calculation report.
Single shear plates, shear end plates and skewed bent plates.
Single and double angles on the beam web.
Beam seated on an unstiffened or stiffened seat angle, with a top angle for stability.
Tee section bolted or welded to the support, with the stem on the beam web.
Fully restrained moment connections: welded flanges or bolted / welded flange plates, with column stiffeners and doublers when needed.
Partially restrained top-and-seat angle connections with web angles, including connection stiffness.
Flush and extended end-plate moment connections (AISC Design Guide 39): all fifteen bolt patterns, with or without stiffeners, and the column stiffeners and doublers they need.
Double-tee moment connections for special and intermediate moment frames (AISC 358-22 Chapter 13): T-stubs with prying, the stiffness check, column flange yield lines, continuity plates and the panel zone.
Beam web splice plates, bolted or welded on each side.
Column and chord splices with bolted flange plates.
Tee-chord truss joints: support connections and panel points with welded web members.
Ends of angles, tees, wide flanges, HSS and plates in tension, bolted or welded to a gusset.
Vertical bracing gussets at beam-to-column joints, distributed with the Uniform Force Method.
Chevron (V and inverted-V) gussets at the beam: beam shear and web checks from the chevron effect.
Horizontal bracing gussets wrapped around the column, with each leg designed as a beam.
Tee, double-angle or plate hangers from a beam flange.
Beam ends bearing on concrete or masonry walls.
Round and rectangular HSS struts in tension with a bolted end plate.
Columns landing on a beam, with bearing stiffeners or doublers when the web needs help.
Crane rails on runway girders: hook bolts, clips and clamps, and rail splices.
Column base plates on a concrete pier or footing under axial load, moment and shear, with anchor rods.
Column bases embedded in a concrete footing for moment-resisting frames.
Base plates at braced frames, with the brace gusset on the column flange or web.
Bracket plates on a column flange, bolted or welded.
Eccentrically loaded bolt groups of any pattern and load angle.
Eccentrically loaded weld groups: lines, C, L and box shapes.
Lap, splice and tension joints: shear, tension, slip and bearing in one place.
Fillet and partial-penetration welds loaded at an angle, with the base metal.
Pin-connected plates and eyebars, including the proportioning limits.
Welds and bolts that join the parts of built-up members, including cover plates and tie plates.
Rectangular and round openings in beam webs, plain or reinforced.
Documents
Elevations, plans and sections drawn to scale, with realistic bolts, weld symbols and dimensions that do not collide. Open the DXF in your CAD program or print the PDF sheet.
Firm name, logo, sheet size and revision block, set once in your own defaults and adjusted per project when a job needs it.
A clear PDF report for each connection: inputs, every check with its result, the governing case and the references, in the order a reviewer expects.
Design a whole connection schedule from a table, then export the sheets and reports together.
Working with ILX Connection
Pick the design method per connection; load combinations come along.
Enter in feet and inches or millimetres; switch at any time.
Bolts, welds, materials, report and title-block settings inherit from your defaults, with project overrides.
Let ILX Connection propose a layout that works, then fine-tune it.
Results update as you type, with the governing check and a hint on what to change.
Projects, search, pinned items, version history and a recycle bin keep your work safe.
