1. A beam of b = 40 cm, h = 70 cm and 10 m length between the faces of the supports was cast monolithically with the 60 x 60 cm columns. The beam is continuous at the right support (B) and joins a column at the left support (A). It supports an ultimate factored load Wu = 10 T/m, which includes its own weight. The frame analysis yields moments at the faces of the supports Mu = 78 T - m. The flexural design results in an area of 8 Ø 1" steel in two layers for the negative moment reinforcement. The material strengths are f'c = 212 kg/cm² and fy = 4200 kg/cm². Calculate the cut-off point (distance from the face of the support, in cm, without decimals) for 50% of the As- (lower layer) at support B. The covers and spacing of the bars comply with the minimums established by the ACI. ½" stirrups. Use the simplified expressions for Id . ( Ø 1" = 2.54 cm )]
