Optimum Base Width of Gravity Retaining Walls of Narrow

Aug 08, 2016· The optimum dimensions of narrow backfill width gravity retaining walls backfilled with recycled materials are obtained by considering the four modes of failure, viz overturning of the wall about its toe, sliding of the wall on its base, eccentricity of the resultant force and bearing capacity failure below the base slab. An analytical method is presented to obtain a …

HOW MUCH CLEARANCE DO YOUR BEARINGS NEED?

The wall is thickest at 90 degrees from the split and drops off a prescribed amount toward each parting line, depending on the bearing’s intended appliion. This drop-off is called “eccentricity.” In addition, there is a relief at the parting lines. Eccentricity is used to tailor the bearing shell to its mating hardware and to provide
