Foundation Checks <br />Sliding <br />The shear demand and ultimate dead load are as described above. The <br />ultimate dead load P_UD for GL 1.5 can be increased for sliding to account for <br />the grade beam and some tributary with of slab over the grade beam and <br />adjacent to the shear wall <br />≔H LS =VLS _T 1 9 9 .2 78 k i pkipkipkip <br />≔H I O =VI O _T 9 3 .5 13 k i pkipkipkip <br />＝P UD _s li d e 1 .1 ⎛⎝+++P UD P gb P gb_sla b P sla b⎞⎠ <br />≔P gb =⋅⋅⋅1 2 i nininin 1 2 i nininin 1 5 0 p c fpcfpcfpcf 67 .7 5 f tftftft 1 0 .1 63 k i pkipkipkip <br />This is the weight from the 12"x12" grade beam that extends down GL 1.5 <br />≔P gb_sla b =⋅⋅⋅4 i nininin 5 f tftftft 15 0 p c fpcfpcfpcf 6 7 .7 5 f tftftft 16 .93 8 k i pkipkipkip <br />This is the weight from a 5' tributary width of the slab over the grade beam <br />≔P s la b =⋅⋅⋅4 i nininin 3 f tftftft 1 5 0 p c fpcfpcfpcf L f 4 .7 3 7 k i pkipkipkip <br />This is the weight from a 3' tributary width of the slab adjacent to the <br />foundation <br />≔P UD _s li d e =1 .1 ⎛⎝+++P UD P g b P g b_sl a b P sl a b⎞⎠5 4 .5 26 k i pkipkipkip <br />Compute Foundation Sliding Capacity <br />＝H C E ⋅⋅P UD f ⎛⎝+C v 1⎞⎠ <br />≔f 0 .25 foundation coefficient of friction per geotech report <br />41-17 allows the sliding capacity to be increased by 1+C_v for an upper <br />bound capacity <br />29 of 100 <br />1327 S Grand Ave <br />12/12/2024
