IRC-112-2011 & BS-EN-1992-2 (Provisions For Bearing Stress Check) Design Resistance (F)

The document discusses provisions for bearing stress checks from IRC-112-2011 and BS-EN-1992-2. It provides the design resistance (FRdu) for M50 concrete with two different values for fcd given by the bearing manufacturer and proof checker's interpretations. It also discusses partially and fully loaded bearing areas, force dispersion, and discontinuities. Finally, it outlines steps for a case study on analyzing stresses in a corbel including visualizing stress flow, sketching a strut-and-tie model, selecting tie areas, checking nodal zone and strut stresses, and ensuring adequate tie anchorage.

IRC-112-2011 & BS-EN-1992-2 (Provisions for Bearing Stress Check)

Design Resistance (FRdu)


 fcd = 22.33MPa (for M50)

Bearing Manufacturer’s Interpretation

fcd2 =37.95MPa

1170

fcd1 = 21.1MPa

Proof Checker’s Interpretation


Partially Loaded Area – Force dispersion

Partial Discontinuity

Full Discontinuity

4. Case Study – Corbel

 Visualize flow of stresses


 Sketch an idealized strut-and-
tie model
 Select area of ties
 Check nodal zone stresses
 Check strength of struts
 Provide adequate anchorage
for the ties
