The external wall <br /> load includes the wind load effect, but also accounts for the additional stiffness added by the exterior <br /> sheathing. In both cases, the members are adequate to support the load of the structure. Most of the new <br /> load added to the existing structure is in the form of dead load added to stiffen and strengthen the existing <br /> floor joists, and a very small percentage of new live load area is being added. The new live load is <br /> primarily supported by new beams and posts, as specified in the plans. <br /> If there are any questions regarding this, or if we may be of further assistance, please contact this office. <br /> Sincerely, <br /> West Coast Structural Engineering Inc. <br /> c <br /> io indquist, PE <br /> Engineer <br /> 1 /,/ 17,010 <br /> p,.
