Vertical Resultants for Uplift Limit State Design of Concrete Foundations in RFEM 6
Vertical resultants for the evaluation of the uplift limit state design under a single foundation in RFEM 6
The image shows a graphical display of the vertical resultant force Vd for the uplift limit state design (UL7400) of a single foundation in RFEM 6. The isoband displayed below the foundation plate illustrates the applied vertical load.
A positive value of Vd shows a sufficient stabilizing load against uplift limit state. The larger Vd is, the greater the safety margin against buoyancy.
If V d is negative, the resultant force acts to lift the structure, meaning the design check is not fulfilled. In this case, the displayed value directly indicates the additional load required to fulfill the design check.
