DESCRIPTION:PARAMETERS:

V = KN (design ultimate shear)w = KN/m (factored uniform load adjacent to design shear)fcu = MPa (characteristic strength of concrete)fyv = MPa (characteristic strength of link reinforcement)bv = mm (width of web)d = mm (construction height)

= mm (main bar diameter)n = pcs (total quantity of main bar)

= mm (link or stirrups diameter)n = pcs (total number of link legs)C = mm (concrete cover at side)

(2.4.2.2) gm = (partial safety factor for shear strength of concrete)(2.4.2.2) gs = (partial safety factor for strength of reinforcement)

Element Type :

CALCULATION:(Eq. 3) v = V / (bv d)

v = 300.0x10 / (250 x 600) = 2.000MPa

As = 3(20/4) = 942.5mm(Table 3.8) vc = [0.79/gm] [100As/bv d]^ [400/d]^ [fcu/25]^

vc = [0.79/1.25] [(100x942.48)/(250x600)]^ [400/600]^ [35.0/25]^vc = 0.606MPa

Asv = 2(12/4) = 226.2mmv - vc = 2.000 - 0.606 = 1.394 > 0.400 , use 1.394

(Table 3.7) s = Asv(fyv/s) / [bv(v - vc)]s = 226.19(250/1.15) / (250.0 x 1.394) = 141mm < (smin = 0.75d = 450mm)
