# Axial Capacity Insufficient in Shearwall

Axial capacity insufficient message is given for columns, shearwalls and shearwall groups by giving the name of solid and element.

*P1 Basement Floor Axial Capacity Insufficient*

**TBDY 2018 7.6.1.1 –** The cross-sectional area of the shearwall after the voids are removed, Ndm is calculated under the joint effect of G and Q vertical loads and E earthquake effect G + Q + E, taking into account the live load reduction coefficients defined for live loads in TS 498. It will satisfy the condition Ac ≥ Ndm /(0.35 fck ), being the largest of the axial compressive forces.

*Ac ≥ Ndm /(0.35 fck )*

If the condition is not met, the wall area (Ac) or concrete class should be enlarged.

### Solution:

The cross-sectional area of the element, whose name and solid is given, should be increased by increasing the dimensions.

Increasing the concrete class contributes to the fulfillment of the condition.

#### Icons:

**Ac =** Gross cross-sectional area of the shearwall

**Ndm = ***N *_{dm} The largest of the axial compressive forces calculated under *G* + *Q* + *E* , the joint effect of *G* and *Q* vertical loads and *E* earthquake effect , taking into account the live load reduction coefficients defined for live loads in TS 498.

**fck =** Characteristic cylinder compressive strength of concrete
