First is determining where to safely set up the crane relative to the shoulder of the slope and second is making sure that the outrigger float loads are distributed down through the blocking or load spreaders such that they don’t exceed the allowable soil bearing pressure. Reading down the table, you see that the code calls for a 12-inch-wide footing under a two-story wood-frame house in 2,500-psf-bearing soil. 3 requires an assumption regarding the shape of the spread footing to establish the required footing dimensions. Frost penetrations. The total load for each tributary area is then divided by the area of each footing in order to determine the load psf imposed on the soil. Closed-form solutions based on the Boussinesq equations are presented in most introductory soil mechanics textbooks for this case. The AASHTO LRFD design specifications [1] define constructed foundations as spread footings, driven piles and drilled shafts. The footing is continuous.

As a rule, a spread footing is a quite rigid element therefore, the applied soil stresses are almost linear and in case of a symmetric (with respect to the pedestal) footing, they are or-thogonal. This program assumes that the spread footing is in fact "rigid", so that the bearing pressure is distributed linearly on a homogeneous soil. The spread footing that the forms sit upon should have it's bottom elevation placed 8" lower than the average annual frost depth. The top surface of footings shall be level. The worst case of rising damp occurs when water ponding occurs at the footing level. Make the bottom of the footing hole the same size as the footing form or larger. A strip footing is also provided for a row of columns which are so closely spaced that their spread footings overlap or nearly touch each other.

Spread Footing: As the name suggests, a spread is given under the base of the foundation so that the load of the structure is distributed on wide area of the soil in such a way that the safe bearing capacity of the soil is not exceeded. The purpose of a foundation is to distribute the loads of the building or structure to the soil in such a way that the soil will bear the load. This load produces a bearing pressure q along the bottom of the footing, as described in Sec­ tion 5. Cover the container with plastic and place in a warm spot in bright, indirect light.
