Ve

Detailed information on shear force control according to TDY is printed. For shearwall with high ductility level Hw / Lw> 2;
And = betav. Vd. Betav = 1.5, as [(Mp) t / (Md) t], but betav = 1.0 is taken for buildings where all earthquake loads are carried by shearwalls.
And (R = 2): It is the found shear force value calculated according to R = 2.
With Ve and (R = 2) whichever is smaller, that Ve is used in the shear force control.

Ve cap value

The shear force obtained by magnifying the shear force calculated from the earthquake with vertical loads by 1.2D or 1.4D times.

Vr

It is the shear strength value of the shearwall section.
And> Vr means that it does not provide cutting safety in the shearwall.

4.3.4.9 factor

For shearwall with high ductility level with Hw / Lw <= 2;
And its value is the value calculated from the most unfavorable load combination.
Factor 4.3.4.9 : For walls with Hw / Lw <= 2, the end forces are increased by the coefficient [3 / (1 + Hw / Lw)] according to the R coefficient. However, this value is not taken higher than 2.

VeMax

It is the maximum shear force that the shearwall can take, calculated according to TBDY Equation 7.18.
