Here, the total overturning moment at the base of the shearwall with coupling beam MDEV, M1 and M2 as the sum of the bending moments obtained at the base due to the earthquake effect in the shearwall parts forming the wall with coupling beams, and NV as the sum of the shear forces formed in the coupling beams under the earthquake effect along the whole wall height. Corresponds to equal tensile and compression axial forces formed at the base of the shearwall parts. c shows the distance between the cross-section gravity centers of the shearwall pieces.

In the program, this calculation is made automatically when the gap is selected and the results are detailed in the earthquake regulation report.

According to this control, our core shearwall is considered as a compound shearwall. However, as stated before, in order to stay in the safe zone, due to the fact that the shearwall with and without coupling beams work together in the X direction, an arrangement suitable for the shearwall without coupling beams is made in the selection of R and D.

Selected R and D Coefficients
A13 special shearwall selection is made for both directions.
