For spacing (δsv) of inclined stirrups in a shear beam, which of the conditions follows:
i) δsv ≥ 300
ii) δsv ≥ 0.75 d
iii) δsv ≥ \(\frac{{0.87{f_y}{A_{sv}}}}{{0.4b}}\)
iv) δsv ≤ \(\frac{{0.87{f_y}{A_{sv}}}}{{0.4b}}\left( {\sin \alpha + \cos \alpha } \right)\)
where b – width of the beam, d – the depth of the beam, Asv – Area of stirrups, fy – grade of steel and α – the inclination of stirrups w.r.t horizontal bars.1
