Shear Safety Tab

Specifications

Hw

It is the total high value of the shearwall throughout the structure.

Lw

It is the length value of the shearwall in plan.

(Mp) t

It is the hardening moment capacity value calculated at the base section of the shearwall.

(Md)t

It is the moment value calculated under the combined effect of vertical loads and earthquake loads multiplied by the load coefficients calculated at the base section of the shearwall.

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)

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.

Vr.

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