b'The governing design requirements in Canada for the embedded steel plate anchorage and associated concrete failure modes are found in CSA A23.3 (2019) Annex D.FIGURE 2:Large axial loaded embedded plate to beam connection. regardless of the style, there are two distinct parts tothedesigntheconcretesideandthesteel side. While the design of the steel side is relatively straightforwardforsimplebeamendconnections, with the design guidance and tables found in the CISC Handbook of Steel Construction being mostly applicable,thedesignoftheanchorageonthe concrete side is much more complex. Thegoverningdesignrequirementsin Canadafortheembeddedsteelplate anchorageandassociatedconcretefailure modes are found in CSA A23.3 (2019) Annex D. For the design of the simple connection shown in Figures1and2, for example, the following limit states need to be assessed (refer to clause D.6 and D.7 of CSA A23.3 for tension and shear design requirements, respectively):i.Resistance of the steel anchor (stud) in tension.ii.Resistance of the steel anchor (stud) in shear.iii.Unreinforced concrete breakout in tension.iv.Unreinforced concrete breakout in shear.v.Concrete sideface blowout (anchor in tension).vi.Anchor pull out resistance (anchor in tension).vii. Concrete pry-out (anchor in shear).viii. Anchorage(stud)combinedshearand tension failure.ix.Concrete reinforcement, if required to anchor the concrete breakout in shear.x. Steelembedmentplateflexure.xi.Interaction of the anchor (stud) group under both shear and tension load. xii. The steel connection to the beam limit statesvaries depending on the connection used.Thus,todesignasimpleembeddedsteel connection is quite complex, unless the designer isveryfamiliarwithAnnexD;forinstance,in order to assess these limit states, there are over 20 equations to evaluate with over 50 separate variables.
