Footings - ResultsSoil BearingIn RISAFoundation, the Allowable Soil Bearing values and the Gross vs Net bearing designation is controlled by the SoilRegion.OverburdenOverburden is the weight of soil or other dead loads (e.g. pavement) which exist above the footing in its final (constructed)condition. RISAFoundation applies the overburden pressure uniformly on the footing, except for at the pedestal. Theoverburden is automatically included in the DL category for service load combinations. Typically it is not included in thedesign combinations.Passive Resistance of SoilFor additional sliding resistance you may enter the passive resistance of the soil as a lump sum value. RISAFoundationapplies this value in both directions.Coefficient of FrictionRISAFoundation multiplies this coefficient of friction by the total vertical forces to determine the soil sliding resistance.Local AxesThe “A,B,C,D” notation provides a local reference system for the footing. The local z axis is defined as positive from Btowards A, and the local x axis is defined as positive from D towards A. The origin for the local axes is the geometric centerof the footing.40 RISAFoundation v4
Footings - ResultsIt is important to realize that the local footing axes do NOT necessarily correspond to the Global axis of the RISA model orthe local axis of the column member.LimitationsNon-Linear EffectsThe Joint Reaction results can differ from the design results used for the OTM safety factor calculation. The reason for this isthat the OTM safety factor needs to determine whether each component (P, V, or M) of each load creates a stabilizing or destabilizingmoment.General Reference Manual 41
