b'Design Example 3Calculate Foundation LoadSingle Story Slab on Grade The single story house is located in North Texas The foundation consists of an 18 tall x 15 wideturned down footing reinforced with #4 rebars. TABLE 6 The concrete slab floor is 4 thick and is carpeted. The exterior walls are 2 x 4 studs on 16 centerswith sheathing, insulation and drywall. The exterioris typical brick veneer, The roof has a 3 in 12 pitch and is framed with 2x 8 rafters and 2 x 6 ceiling joists.There is no atticstorage, but there is 10 of blown in insulation.Thespan is 12 feet with a 2 foot overhang.Calculate the Foundation Loads - Referring to TABLE 5theLoadTablesinChapter6,estimatethefoundation service (working) load, the live load TABLE 2and the temporary soil load.(No Snow Load)1.
