RCC Numerical – If xu is limited to 0.39, calculate pt and Mu. Assume M20 – Fe415 concrete and steel.

 If xu is limited to 0.39, calculate pt and Mu. Assume M20 – Fe415 concrete and steel. Given: Concrete grade: M20 (characteristic compressive strength fckf_{ck} = 20 MPa) Steel grade: Fe415 (yield strength fyf_y = 415 MPa) Maximum depth of the neutral axis xu=0.39dx_u = 0.39d 1. Calculate ptp_t (Area of Steel per Unit Area…
