Post Embedment Calculation <br /> Determine the minimum posthole diameter and embedment depth for the eave wall posts <br /> per ASAE EP486.1 <br /> Since there is no slab,the post will be considered non-constrained at the top <br /> The backfill will be concrete full depth. <br /> Design Criteria: <br /> Sy= 1500 psf-vertical soil bearing capacity <br /> S= 150 psf-lateral soil bearing capacity <br /> Mpost= 548 ft-lbs-Moment at top of one posthole <br /> Va= 304 lbs-Lateral load on post at top of posthole <br /> Posthole dia.= 2 ft. <br /> b= 0.50 ft-maximum width of post in soil <br /> Ah9= 3.14 ft2-area of footing <br /> d= - ft-depth of footing to be determined below <br /> Per Sections 4.2.2.1 and 4.2.2.2,allowable lateral soil bearing capacities may be increased <br /> by 2 for isolated posts(spaced at least 3 ft.apart),and by 1.33 for wind loading <br /> SLAT 476 psf-factored lateral soil bearing capacity <br /> Minimum embedment depth required for lateral load,non-constrained at the top, <br /> concrete backfill,per Section 6.6.2 <br /> dmin= [((6 x Va)+((8 x Mpost)/d)))/(SLAT x b)]^1/2(iteration to dmin_L= 3.58 ft.-minimum depth requried for <br /> lateral load <br /> Allowable vertical soil bearing pressure for gravity loads <br /> Sy= Sy x An9 X(1+(0.2 x(d-1)) <br /> • <br /> Sy= 1500 psf-vertical soil bearing capacity • <br /> An9= 3.14 ft2-area of footing <br /> d= minimum depth for vertical bearing requirements <br /> Maximum vertical load on footing from gravity load Pfooting= 3,780 lbs-vertical load on footing <br /> Posthole depth for this building= 5.00 ft-minimum depth to bottom of footing. <br /> Vertical capacity for footing Panow= 8,482 lbs->Pfooting-OK <br /> Page 8 of 13 <br />
