Shear Strength for Shearwalls
A ch = Gross cross-sectional area of each curtain segment, slab or each slab in a hollow slab
f ctd = Design tensile strength of concrete
f ck = Characteristic cylinder compressive strength of concrete
f ywd = Design yield strength of transverse reinforcement
V e = Shear force taken as basis for transverse reinforcement calculations in columns, beams, junctions and walls
V r = Shear force ofcolumn, beam or curtain section
ρ sh = Volumetric ratio of horizontal web reinforcements in the wall
TBDY Article 188.8.131.52 - Shear strength of wall sections, V r , shall be calculated by Equation (7.17) .
The design shear force Ve defined in 184.108.40.206 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.
