Job Name: Muller Santa Ana Job Number: 2021-SRS004 Date: 11/9/21 Canopy Design (See Appendix A): The canopy was designed in RISA-3D. The results for that analysis as well as model views of the framing are provided in Appendix A. In the RISA model, the structural steel members and nodes are labeled based on the gridlines in order to make association easier. For instance, the column at the intersection of Lines A and 13 is column "Col A13." The beams along Line 7 are "B7-1, 2, 3, etc." starting from Line A and counting higher toward Line F. The jack beams that span over the end drive aisle area are labeled B-Jack-Line C or D. The purlins are labeled slightly different. The first purlin line at the west side, for instance, is "P1-#" with the first bay at the north all being number 1 purlins; in other words, the purlin at the west most line that is furthest north is P1-2 (there is no purlin in the northern most bay at Line 1) and the purlin at the fifth line from the west and in the northern most bay is P5-1. In the model, the lateral resisting system in the east/west direction is a Steel Ordinary Moment Frame. These moment frames occur along number Lines from 1 to 15. The lateral resisting system in the north/south direction is a Steel Ordinary Concentrically Braced Frame. Lines A, C, D and F all have rod bracing braced frames. Lines C and D have significantly more rod braces due to larger tributary area and in an effort to reduce lateral loading to the columns along the ramp. The results for member sizes based on the RISA model are summarized below: RISA Member Results: Hot Rolled Members: Columns: W12x40 Beams at all Lines: W21x44 Jack beams at Lines C and D: W21x101 Drage beams at Braced Lines: W10x19 Rod bracing at roof level and Lines A, C, D and F: 3/4" diameter Materials: W sections are A572 Gr 50, rod bracing is A572 Gr 50. Light Gauge Members: Majority of purlins: 800S350-54 Purlins at perimeter: 800S350-97 Purlins in northwest and northeast corners btwn Lines 2 and 3: 800S350-68 Blocking at purlin midspan: 600S200-54 Page 1 2677 N Main St - 101110159-60 & 20175958-5902/07/23
