Bearing Pressure
基础底面平均接触压应力。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Average base pressure | p = N / A, where N is the transmitted vertical force and A the base area | GB 50007-2011, Code for design of building foundation |
| Bearing capacity check | The average base pressure must not exceed the modified characteristic bearing capacity | GB 50007-2011, Code for design of building foundation |
| Eccentric loading | p_max/p_min = (N/A) · (1 ± 6e/B), where e is the eccentricity and B the base width | GB 50007-2011, Code for design of building foundation |
| Distribution assumption | Under a rigid footing the base pressure is assumed to vary linearly | GB 50007-2011, Code for design of building foundation |
