Design for shear (pile cap:EC2)
Shear design calculations are performed for the STR load combinations.
Determination of Design Shear Stress
| Shear stress acting on side 1 in direction X | vEd,x1 |
|
ΣP n,1 / (d x *L y ) |
| Shear stress acting on side 2 in direction X | vEd,x2 |
|
ΣP n,2 / (d x *L y ) |
| Shear stress acting on side 1 in direction Y | vEd,y1 |
|
ΣP n,1 / (d y *L x ) |
| Shear stress acting on side 2 in direction Y | vEd,y2 |
|
ΣP n,2 / (d y *L x ) |
Maximum allowable shear resistance
vRd,max = 0.5 * v * fcd1
where:
fcd = αcc * fck / γc
αcc = 1.0 (EC2); αcc = 0.85 (supported NAs)
γc = 1.5
v = 0.6 * [1 - (fck/250)]
Check for Shear
The shear capacity check procedure is identical to that for pad bases, see: Design for shear (pad and strip base:EC2)
