<br /> <br />Table 4,10 provides the calculated maximum <br />vertical loads for typical manufactured home <br />widths (12 feet and 14 feet) and chassis I-beam <br />spacing 75V2-, 82-, and 99-inches based on the <br />spacing of vertical members along the length of <br />the manufactured home. The elevated foundation <br />design must support these loads. Note that design <br />roof live loads and wind loads do not occur <br />simultaneously. <br /> <br />Because a double section manufactured <br />home is essentially two connected single sec- <br />tion manufactured homes, this chapter <br />presents design criteria based on typical single <br />section widths. When a double section <br />manufactured home is being considered, the <br />recommendations provided herein should be <br />followed for each section. <br /> <br />Table 4.10 <br /> <br />MAXIMUM VERTICAL MEMBER LOAD (pounds) <br /> <br />Longitudinal Manufactured Home Width (ft.) <br />Spacing (ft.) 12 14 <br />Wind load = 15 psf OIassis I-Beam SDacinll: (in.) <br />Roo f Li ve Load = 20 ps f 75 1/2 82 99 75 1/2 82 99 <br /> 5 2500 2900 <br /> 6 3000 3480 <br /> 7 3500 4060 <br /> 8 4000 4640 <br /> 9 4500 5220 <br /> 10 5000 5800 <br />Wind Load = 25 psf <br />Roof Live load = 20 psf <br /> 5 2744 2669 2520 3044 2969 2900 <br /> 6 3293 3203 3024 3653 3563 3480 <br /> 7 3842 3737 3528 4262 4157 4060 <br /> 8 4391 4271 4032 4871 4751 4640 <br /> 9 4940 4805 _4536 5480 5345 5220 <br /> 10 5489 5339 5040 6089 5939 5800 <br />Roof Live load = 30 psf <br />Wind Load = 15 or 25 psf <br /> 5 2850 3300 <br /> 6 3420 3960 <br /> 7 3990 4620 <br /> 8 4560 5280 <br /> 9 5130 5940 <br /> 10 5700 6600 <br />Roof Live load = 40 psf <br />Wind Load = 15 or 25 psf <br /> 5 3200 3700 <br /> 6 3840 4440 <br /> 7 4480 5180 <br /> 8 5120 5920 <br /> 9 5760 6660 <br /> 10 6400 7400 <br /> <br />47 <br />
