Steel Buildings in Europe

Part 5: Joint Design 5 - 83 5 COLUMN SPLICES (BEARING TYPE) Column splices are designed assuming they must resist both the axial compression and, where appropriate, a nominal moment from the connection to the beams. In bearing type splices, the axial load is transferred directly between the ends of the column sections (with a division plate if necessary due to the change of serial size) and not via the splices plates. The plates provide the splice with adequate stiffness and tying resistance. 5.1 Recommended details h h b b t lc lc f,uc w,lc b p uc uc t h 2 p p 1 2 3 4 5 6 7 1 Web cover plate width  0,5 h uc 2 Multiple packs thickness t pa 3 Web cover plate at least 4 no.
