Concrete strut capacity: ( \nu = 0.6(1 - f_ck/250) = 0.6(1-0.14)=0.516 ) ( f_cd = 35/1.5 = 23.3 \text MPa ) ( \theta = 22^\circ ) initially: ( \cot \theta = 2.5 ) Check ( \frac\tau_t,Edf_cd \sin\theta \cos\theta + \frac\tau_v,Edf_cd \sin\theta \cos\theta \le 1 )? No – better use: [ \fracT_EdT_Rd,max + \fracV_EdV_Rd,max \le 1 ] But easier: ( \tau_total = \sqrt\tau_t,Ed^2 + \tau_v,Ed^2 = \sqrt2.31^2 + 0.74^2 = 2.43 \text MPa ) Allowable ( \tau_max = 0.5 \nu f_cd = 0.5 \times 0.516 \times 23.3 \approx 6.0 \text MPa ) → OK.
