Basically, <br /> all concrete walls assumed full tributary span of L/2 L/2 <br /> floor members and roof members. <br /> Design code: IBC 2021 <br /> Roof LL(snow ground):25 psf <br /> Floor LL:40 psf <br /> Patio/Deck LL:60 psf <br /> Floor/Roof DL: 15 psf <br /> Wall DL: 12 psf <br /> Conc Wall DL: 150pcf x 240 in2=250 plf <br /> *see following pages for area calc <br /> Pile#1-2,9-14 21-211 (1 811 + 811) <br /> Roof Trib=0.5*30'=15' <br /> Floor Trib=0.5*20'= 10' <br /> Typical Flr Ht=20' <br /> Pile#3-5 <br /> Roof Trib=2'trib+2'overhand=4' <br /> Floor Trib=0.5*6'=3' Pile and connection requirements per ffeiand connection requirements per <br /> Deck Trib=0.5*10'=5' contractor contractor <br /> Typical Flr Ht=20' <br /> Pile#6-8 <br /> Roof Trib=2'trib+2'overhand=4' <br /> Floor Trib=0.5*20'= 10' <br /> Typical Flr Ht=20' 6'-0" MAX <br /> Pile #1-2,9-14 Pile #3-5 Pile #6-8 <br /> Case 1: Point Load(6'Span) Case 1: Point Load(6'Span) Case 1: Point Load(6'Span) <br /> Pile Reaction=1940 plf*6'=11.7 k Pile Reaction= 1820 plf*6'= 14.6 k Pile Reaction= 1500 plf*6'=9.0 k <br /> Pile Reaction w/SW=2190 plf*6'= 13.2 k Pile Reaction w/SW=2070 plf*6'= 16.6 k Pile Reaction w/SW=1750 plf*6'=10.5 k <br /> Case 2: Uniform Load Case 2: Uniform Load Case 2: Uniform Load <br /> DL= 12*20+15*(15+10*2)=765 plf DL= 12*20+15*(4+3*2+5)=465 plf DL=12*20+15*(4+10*2)=600 plf <br /> LL=40*10*2=800 plf LL=40*3*2+60*5=540 plf LL=40*10*2=800 plf <br /> SL(snow)=25*15=375 plf SL(snow)=25*4= 100 plf SL(snow)=25*4=100 plf <br /> Total load=DL+LL+SL= 1940 plf Total load=DL+LL+SL=1105 plf Total load=DL+LL+SL=1500 plf <br /> Total load w/SW=DL+LL+SL=2190 plf Total load w/SW=DL+LL+SL= 1355 plf Total load w/SW=DL+LL+SL= 1750 plf <br /> Refer to attached calculations for analysis. Refer to attached calculations for analysis. Refer to attached calculations for analysis. <br /> Conclusion: <br /> Based on the loading and geometry of the structure we conclude that the foundation may be stabilized through the use of piles and <br /> connections per R&R. These are to be attached to the stem-wall (grade-beam)at an on-center(o.c.)spacing no greater than 6'-0"o.c.. <br /> L120 ENGINEERING&DESIGN <br />
