Question

The T-section with given dimensions (in mm) is subjected to the following ultimate design forces:

          Bending moment          M = 1250kN.m

          Shear                              V = 320kN

          Torque                         T     = 40kN.m

Characteristic concrete strength     fcu = 35MPa

Conditions                                        Moderate

Fire resistance                                  1 hour

Flexure reinforcement                     Assume Y40 bars

Shear reinforcement                        Assume Y10 links

Aggregate size                                  hagg = 19mm

Design all suitable reinforcement for an interior T-section spanning 2750mm and detail accordingly.
