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, whose name and solid is given, should be enlarged.

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

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
