When V_c1=V_c2 how to determine the value of ho_w? Thanks

Hi, the value of rho_w is always Greater than or equal to 0. It can't be negative. This is worthy to note. Furthermore it is unlikely that V_c1 is equal to V_c2. Because V_c2 is the shear buckling strength considering there is no post buckling shear strength. V_c1 considers tension field action or post buckling shear strength. That being said if you obtain a negative value for Rho_w just take it as zero. And the minimum required Moment of inertia is simply I_st2. A common practice to make life easy is to take I_st as I_st1. This assumes that rho_w is 1. But this is too conservative and can lead to an unnecessarily expensive design.
