Formula 1

For the general condition of load applied directly to concrete in bearing, and considering a supporting concrete area that is wider on all sides than the loaded area, the nominal bearing strength for concrete is given by Equation J8-2:

Rn=0.85fcA1A1/A21.7fcA1R_{n}=0.85 f_{c}^{\prime} A_{1} \sqrt{A_{1} / A_{2}} \leq 1.7 f_{c}^{\prime} A_{1}
