Verification of spread footing for punching shear
The program allows for the verification of spread footing for punching shear. The critical section loaded in shear Ucr is distant from the column edge by one half of the footing thickness. It is loaded by the prescribed moments Mx, My and by the shear force V* provided by:
| where: | A | - | area of footing |
| V | - | assigned vertical force developed in column | |
| At | - | hatched area in fig. |
Dimensioning of shear reinforcement area At
The program checks, whether the cross-section bursting strength is sufficient according to the relation:
|
|
| where: |
|
|
|
|
|
|
| where: | βh | - | the ratio of the longest overall dimension of the effective loaded area, Y, to the overall dimension, X, measured perpendicular to Y |
| a | - | the dimension of the critical shear perimeter measured parallel to the direction of M*v | |
| M*v | - | the bending moment transferred from the slab to a support in the direction being considered |
The analysis is carried out independently in directions xand y, as the decisive one the lower value of Vu is accepted.
