At the limit state of collapse, an RC beam is subjected to flexural moment 200 kNm, shear force 20 kN and torque 9 kNm. The beam is 300 mm wide and has a gross depth of 425 mm, with an effective cover of 25 mm. The equivalent nominal shear stress (t) as calculated by using the design code turns out to be more than the design shear strength (TI of concrete, The equivalent shear force and equialent flexural moment ?
