Job Name: Muller Santa Ana Job Number: 2021-SRS004 Date: 11/9/21 Materials: Light gauge purlins are A653 Gr 55, blocking are A653 Gr 33 Plate Material In Connections: Use A572 Gr 50 Connection Design (See Appendix B): All of the connections were analyzed in RISA Connection. The load combinations in RISA-3D included overstrength combinations for analysis of the connections and these were transferred to Connection. Due to the large volume of connections, only the most heavily loaded connection for each geometry were presented in Appendix B. There are six main connection geometries modeled in RISA Connection: 1. Beam-to-Beam Moment Splices: This occurs at various locations along the moment frame lines and is intended to assist in erection/transportation of beams. These consist of mating plates welded to the ends of each beam with an 8 bolt pattern connecting them in the field. 2. Girder/Beam Shear Tab: This occurs where a carrier beam supports another beam that tees into it. Line 2 is supported by jack beams and use this connection. The jack beams are hung on the beams at Lines 1 and 3 in the same manner. These consist of a shear tab welded inside the flanges of the carrier beam with the supported beam having its flanges cut back and web bolted to the shear tab. The shear tab connections for the braced frame top beams are calculated similarly and an example of that is also included in the Appendix. 3. Single Column Base Plate: Occurs at the base of all columns. These are a simple base plate welded to the column with a 4.5" x 4.5" bolt pattern with four total anchor bolts. 4. Beam-to-Column Connection: This occurs at every beam to column location. These consist of a mating plate welded to the top of the column with an 8 bolt pattern for connecting it in the field to the beam bottom flange. The beam also has web stiffeners welded inside its flanges and in line with the flanges of the columns below. The results for each of these is presented below: RISA Connection Results: Girder/Beam Shear Tab: Shear tab is a 3/8" plate welded full height of the carrier beam with a 1/4" fillet weld all around. The supported beam has its flanges trimmed back. The two are bolted together with four 3/4" diameter A325-N spaced at 4" oc vertically with 1-1/2" minimum edge distance. Single Column Base Plate: 1" thick x 12.5" x 8.5" base plate welded all around to the Page 2 2677 N Main St - 101110159-60 & 20175958-5902/07/23
