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 126.96.36.199 - 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.
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.
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
