Hi guys, having a little bit of a wonder regarding calculation of shear capacities of the reo in a pullout box is (for use in a jumpform application). Looking at manufacture's design guides are bit odd to me - for example Reid's design guide seems to dip into AS4100 bolt/pin connections by including the 0.62 factor seen in clauses 126.96.36.199 and 9.4.1, but with a phi of 0.6 which seems to come from AS3600 for fixing. I've also heard of using phi = 0.36 (I think a doubling up of 0.6 from AS3600 and some other clause regarding an additional 0.6) but nobody seems to be able to point to me where that additional 0.6 is pulled from. Using 0.36 makes enough sense to me, just would like some guidance as to where numbers are being pulled from and/or why Reid seems to mix and match.
