The base plate has a 4.5" x 4.5" anchor bolt spread utilizing <br />four 7/8" diameter anchors. <br />Beam-to-Beam Moment Splices: <br />At W21x44 beams: 1" thick x 7-1/2" wide x 27-11/16" tall mating plates welded to <br />the end of each beam with full penetration welds. These plates bolt together <br />in the field using eight 3/4" diameter A325N bolts. <br />Beam-to-Column Connections: 1" thick x 8.5" wide x 24" long mating plate welded to <br />top of column with full penetration welds all around. Bolted to the bottom flange of <br />the beam in the field with eight A325N bolts: use 3/4" diameter at the W21x44. The <br />plate stiffeners at the beam will be welded to the beam with 1/2" fillets: use 3/4" thick <br />plate at the W21x44. At column B9, the plate can be 21.5" long instead. <br />Hilti Connection Design (See Appendix C): <br />The worst-case loading conditions were analyzed for each existing garage anchorage <br />case. Notice that in many of the anchorage calculations, the anchors show a failure <br />condition in concrete breakout. Hilti Profis, unfortunately, does not check conditions <br />for transfer of the loading to adjacent rebar. Some of those connection will need <br />further analysis here to prove them. <br />Connections at A10, A11, B1, B15, C3, C4, C15, D3, D4 & E1: <br />See Calculations C1 & C2 <br />All of these columns rise above the deck and can be fastened directly into from the <br />top with epoxy bolts. The worst-case loading for these is at A11 and D4. Both of <br />these work. <br />Connection at C12, C13 and C14: <br />These connections do not actually anchor to the concrete at all. Instead, they <br />employ four threaded rod anchor bolts that drop thru the slab and saddle around the <br />concrete beam below. The shear from the columns is transfered from the anchor rods <br />to the slab. <br />Connections at C5 thru C11 (excluding C6-C8) and D5 thru D11: <br />See Calculations C3 and C4 <br />All of these columns rise above the deck and can be fastened directly into from the <br />top with epoxy bolts. Due to constraints at these columns, the standard base plate <br />Page 3 <br />2677 N Main St - <br />101110159-60 & <br />20175958-5902/07/23
