# Shear Strength for Shearwalls

**ICONS**

* A _{ch }=* Gross cross-sectional area of each curtain segment, slab or each slab in a hollow slab

*Design tensile strength of concrete*

**f**_{ctd}=*Characteristic cylinder compressive strength of concrete*

**f**_{ck }=*Design yield strength of transverse reinforcement*

**f**_{ywd}=*Shear force taken as basis for transverse reinforcement calculations in columns, beams, junctions and walls*

**V**_{e }=*Shear force ofcolumn, beam or curtain section*

**V**_{r }=**ρ**

_{sh }*Volumetric ratio of horizontal web reinforcements in the wall*

**=****TBDY Article 7.6.7.1 -** Shear strength of wall sections, V _{r} , **shall** be calculated by **Equation (7.17)** .

**The** design shear force Ve defined in **7.6.6.3 will meet** the conditions given in **Equation (7.18)** :

Otherwise, the wall transverse reinforcement and / or wall section dimensions will be increased to meet these conditions.
