  • What is the difference between bearing stress and ... - Quora

    Mar 22, 2016 · Crushing stress (bearing stress) is a special type of localized compressive stress which occurs at the surface of contact of two members that are relatively at rest. It is taken into account in the design of riveted joints, cotter joints, knuckle joints. etc.For practical applications the limiting crushing stress is approximately twice the elastic limit of a material.

  • Beam Bearing on Concrete - B G Structural Engineering

    The allowable stress on the concrete is taken as 0.85f'c, where f'c is the 28-day compressive strength of a standard laboratory cured 6 in. diameter x 12 in. long test specimen of the concrete used for the bearing surface. A1 is the actual contact area (NB) between the concrete and the steel plate.

  • Compressive Strength of Concrete Cylinders

    The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by breaking the cylinders in a compression-testing machine.
