Wood design values are based on #2 S.P.F. (South) and Southern Pine construction grade wood from NOS Amencan <br /> Forest & Paper Association, current edition. <br /> 3. For 'C' wind exposure category, multiply allowable stud heights by 0.85. <br /> 4. For utility sheds multiply heights by 1.14. For utility sheds in exposure 'C' category wind zones, multiply allowable height by <br /> 0.97. <br /> 5. Stud heights are limited by code and 2 x 4 greater than 10'-0" (stud length) are not shown. 2 x 6 greater than 1B'-0" (stud <br /> length) are not shown. Maximum stud heights less than 6'-6" are not listed. <br /> I <br /> -. <br /> Lawrence E. Bennett, P.E. <br /> CIVIL ENGINEER - DEVELOPMENT CONSUL TANT <br /> P.O.
