Column Splice Connection Calculator

Design a column splice - the bolted cover-plate joint that gives continuity between two columns - to Eurocode 3 (EN 1993-1-8) with SCI P358 §6. Choose a bearing splice (the prepared ends transfer compression in direct contact, through a division plate where the serial sizes differ) or a non-bearing splice (the cover plates and bolts carry the full axial force and moment). The calculator runs the net-tension test (M_Ed vs N_Ed,G·h/2), then verifies the flange cover plates and their bolt group (with the packing and long-joint reductions), the web cover plates, the 25% minimum-resistance rule and the structural-integrity tie - each with its utilisation and a clear PASS/FAIL on an interactive 3D model.
