Ridgc I3eam: 'I'hc intention was lhat the combination of collar ties on each rafler, roof diaphragms, and other framing systems N�ould have made for a non supporting ridge possibility. After speaking wilh another structural engineer, even though he agreed we could do this without a structural ridge, in his opinion it would be casicr to agree with your call on this, under the circumstances. I have indicated a structural ridge throughout the plans (A-2 and A-3), and supported it as indicated via existing posts through the garage. Largcr footings have been indicated on A-2 Poundation. 2. Point loads from multiple Floor Joists: No multiplc floor joists are supporting any concentrated roof loads or othenvise. They are simply indicating positions where walls above in the 2"� Floor exist, or whem window jacks exists. A structural engincer advised that since no roof loads are concentrated on these positions there is no location wherc there is anything close to 3000 Ib loads coming down on these multiple tla�r joist positions. The 3 locations wherc triple floor joists were shown previously may have made it seem that large loads wcrc involved. That is not the case. Originally 1 had them all as double floor joists simply to support slighdy increased dead loads of walls above, not triple. Thc builder indicated a dcsirc to make thcm triple. 1 have reverted them back to double (A-2 First Floor). The builder can make them triple if he so dcsires. 3. G'/. x 15 GLB: this is an altcrnatc mid garagc bcam as indicatcd by the namc on the beam calcs. 1 have inJicated on the plans (A-2 First Floor) that this beam can be uscd as an altematc to the 5 1/8 x 22 Yz GLB through the middle ��f the garagc. If thc builJing dept prefers, this alt can be eliminated as an aption. 4. 2 Dit%rcnt calcs for multiple 2x12's (and 2x10's).'I'hese calcs are for the 10' span and 12' span beams around the patio as indicatcd on the plans and in the bcam calcs thcroselves. The bcam calc sottwarc does not have a selection for 6x I Ys. 'I'h� 12' span calcs support the use of Gx 12 beam on the North side of the patio. Plate connectors ha��e been called out on all previously indicated 45 dcgrec braces at each patio post to further assist and mitigate any addeci loads from current changes by the addition of a supporting ridge. Thc East and West hcams havc becn mcalculated for the (newer) 10' width of the patio. The center bcam is 6a 12 with supporting calc. All indicated on A-2 First Floor. i. Garagc / living space separetion:'/:" GWB has been indicated on A-2 First Ploor wall and multiple tloor joists sup�rting the separation wall above. G. Smoke alarnis: l�he smokc alattns (SD) were alreauy indicated inside and outside of thc 2"'� floor door. A note has becn added :o further identify them,
