End Plate Connection Design Calculator

Design a bolted end plate connection - a plate welded to the supported beam end and bolted to the supporting member - to Eurocode 3 (EN 1993-1-8) with the SCI P358/P398 rules. Switch between a simple (shear) end plate and a moment end plate: the calculator verifies the weld group, the supported beam web shear, the bolt group (shear with the long-joint reduction and bearing), the end plate gross/net/block shear, and - for the moment case - the equivalent tension-zone T-stub (Mode 1 plate yielding, Mode 2 bolt-plus-yield, Mode 3 bolt failure) plus the combined bolt shear-tension interaction, each with its utilisation and a clear PASS/FAIL on an interactive 3D model.
