b'Simplified Tables of Structural Foundation LoadsWhen attempting a foundation load calculation for the first time, it often seems complicated and imposing.Oncethe basics are learned, estimating structural loads is quite easy.The simplest way to prepare a foundation loadestimate is to break the structure into components, determine the estimated weight for each component and thenadd all of the results together.The simplified tables below have been prepared for the most common residentialstructural elements. (See note regarding Building Codes after Table 7 below.)Table 2.
