Bearing Pressure vs Applied Force (F)

Vedi formula →

Formula

## Bearing Pressure Bearing pressure is the compressive contact stress between two surfaces, such as a beam sitting on a support plate. ### Formula **sigma_b = F / A_bearing** where F is the applied force and A_bearing is the contact area. This must not exceed the allowable bearing stress of the weaker material. For steel on concrete, allowable bearing is typically 0.85 f'c (concrete strength) multiplied by area modification factors.

Esempio Risolto

An 80 kN beam reaction on a 100 mm x 40 mm bearing plate.

  1. 01Bearing area = 100 x 40 = 4000 mm^2
  2. 02F = 80 kN = 80,000 N
  3. 03sigma_b = 80,000 / 4,000 = 20 MPa
