Tip

  • Cutting safety control of the columns is done automatically.

Tip

  • Shear force V e to be taken as basis for transverse reinforcement calculation in columns , Eq. It is calculated automatically with (7.5) .

Tip

  • For the calculation of M a and M u in Eq. (7.5) , 7.3.7.2 is applied automatically at the lower and / or upper ends of the column, if Equation (7.3) is fulfilled , and 7.3.7.3 is automatically applied if it is not .

Tip

  • The sum of the shear force calculated from the earthquake increased with D with the vertical loads , Eq. If V e calculated by (7.5) is smaller than V e , this shear force is used instead of V e condition is applied automatically.

Tip

  • Equation (7.6) is applied separately for both directions of the earthquake and the largest ∑ M p value obtained in each direction is taken as the basis in the distribution. Eq. (7.3) 's achieved even though the Eq. (7.5) ' one of M a or M ü 'are account 7.3.7.3 According done automatically.

Tip

  • In the calculation of M pa and M pü moments, N d axial forces which make these moments maximum in accordance with the direction of the earthquake are taken into consideration.

Tip

  • Moment M a at the lower end of columns connected to the foundation is automatically calculated as moment capacities according to 7.3.7.3 .

Tip

  • The shear force calculated by Equation (7.5) , V e , the shear force calculated under the combined effect of vertical loads and earthquake loads multiplied by the load coefficients, is not taken less than V d and it is also automatically checked whether it meets the conditions given in Eq. (7.7) .

Tip

  • In the calculation of the transverse reinforcement in the column confinement zones defined in 7.3.4.1 , if the shear force consisting only of seismic loads is greater than half of the total shear force in seismic condition and at the same time, the condition of N d ≤ 0.05 A c f ck is fulfilled, the contribution of the concrete to the shear strength V c = 0 is taken.

...

And it must satisfy the conditions given by Equation (7.7) . If it cannot be achieved, the earthquake calculation should be repeated by increasing the column section dimensions as necessary.         

...

Vr is the shear strength of the column section . It is calculated with the following steps according to TS500 .

...

As stated in TBDY 7.3.7.6 , in the calculation of transverse reinforcement in the column confinement zones, the contribution of concrete to the shear strength is V if the shear force consisting only of earthquake loads is greater than half of the total shear force in earthquake condition and at the same time the condition N d <0.05A c f ck is met. c = 0 is taken.
