WebFig.1. Punching Shear Failure Zone for Slabs above and below the column. The ‘d’ is the effective depth of the slab. The punching shear perimeter is formed at a distance of d/2 from the edges of the column or the pedestal. In the figure-1, D ped is the depth of the pedestal. Design Considerations for Punching Shear in Slabs WebTerzaghi modelled only the general shear failure mode, not local or punching shear failures. This is usually adequate as long as a suitable settlement analysis is also undertaken. The above equations are presented in terms of effective stresses. It is possible to convert this to a total stress analysis in cases where the soil conditions are ...
WebSep 13, 2013 · The failure zone does not extend above the base of the foundation. Shear resistance of the soil above the base of the foundation is neglected. The soil above the base of the foundation is replaced by a uniform surcharge. The principle of superposition holds good.
