Geotechnical Parameters For Structural Desisn <br />For conservative purposes, the following values can be used for structural design, as needed. <br />a. Allowable vertical bearing earth pressure: 1.500 psf <br />An increase of one+hird is permitted when using the alternative load combinations that <br />include wind or earthquake loads. <br />b. Lateral bearing passive earth pressure: 100 psf per foot into competent materials below <br />the finished ground surface. <br />An increase of one third is permitted when using the altemative load combinations that <br />include wind or earthquake loads. <br />ln addition. the lateral resistance values are permined to be increased by the above- <br />recommended value for each additional foot of depth to a maximum ol I 5 times the <br />above-recommended value. <br />c. Lateral Sliding Resistance: cohesion = 130 psf <br />l he cohesion value is to be multiples bv the contact area. <br />ln no case shall the lateral sliding resistancc exceed one-halfthe dead load <br />d. Soil unit weight: 120 pcl' <br />Minimum depths fbr new building footings should be 24 inches below the adjacent finished <br />grades. Minimum widths for isolated columns/pad footings should be 24-inch, and lbr <br />continuous wall footings should be l5-inches for one-story, l8-inches for two-story. and 2l <br />inches for three-story portions, if any. <br />Where located adjacent to a utility trench, footings should be extended to have the footing <br />bottom located below a one-to-one imaginary plane projected from the inside bottom edge ofthe <br />trench. <br />Minimum reinforcement for continuous footings should be two #5 re-bars at top and two #5 re- <br />bars at bottom- <br />New Buildinq Slabs-on-Crade <br />Page 5 <br />BUILDING IOUNDA'llON DI]SIGN Gl.JlDF-LINES <br />New Building Footings
