# Axial Capacity Insufficient in Column

The axial closing is insufficient message is given for columns, walls and curtain groups, namely floor and element.

*S1 Basement Floor Axial Capacity Insufficient*

**TBDY 2018 7.3.1.2 -** The gross cross-sectional area of the column, Ndm Considering the live load reduction coefficients defined in TS 498 for live loads, the joint effect of vertical loads G and Q and E earthquake effect is the calculation of axial pressure forces calculated under G + Q + E. the largest, it will meet the condition Ac ≥ Ndm /(0.40 fck).

*Ac ≥ Ndm / (0.40 fck)*

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

In addition, the conditions given in TS 500 for increased vertical loads (1.4G + 1.6Q) are checked.

**TS 500 7.4.1 -** Axial Pressure and Bending

Nd ≤ 0.9 fcd Ac condition must be met.

### Solution:

The cross-sectional area of the element given its name and solid 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 column

**Ndm = ***N *_{dm} Considering the live load reduction coefficients defined for live loads in TS 498, the joint effect of vertical loads *G* and *Q* and *E* earthquake effect is the largest of the axial pressure forces calculated under *G* + *Q* + *E*

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

**Nd =** Maximum column axial force under increased vertical loads

**fcd =** Design compressive strength of concrete
