What's inside

Everything in one calculation.

No black boxes. Whether you're designing a glulam moment connection, an eaves connection, or a simple timber splice, every step is shown with its governing EC5 equation, inputs, and output - so you can check it, sign it off, and submit it with confidence.

EC5-Compliant Calculations
Full Johansen yield theory, Hankinson embedment reduction, rope effect capped at 25%, and nef row reduction - all per EN 1995-1-1:2004 + A2:2014 with UK National Annex.
Professional PDF Report
Every formula shown step-by-step with EC5 clause references, spacing check tables, and pass/fail status. Suitable for submission to building control or a checking engineer.
DXF Drawing Export
Export connection geometry directly to DXF for use in CAD or BIM workflows. Clean, layer-structured output ready for detailing and coordination.
Polar Moment Bolt Group
Moment M, shear V, and axial N distributed elastically across the bolt group. Full resultant force per bolt with angle-dependent Hankinson embedment.
Grid & Circular Patterns
Grid and circular bolt arrangements fully supported. Circular patterns automatically compute chord spacing for EC5 Table 8.4 minimum distance checks.
Eaves Moment Connection
Glulam eaves moment connection with split-column and beam-slotted sub-configurations. Full M + V + N combined capacity design to EC5 §8.2 / §8.3.
