Problem $1$ Determine, according to the NTC$-$Concrete, the cutoff points of the longitudinal blue bars located in the bottom bed of the beam. Note that only two cutoff points must be established, corresponding to the two #$8$ bars painted in blue. Consider that the beam is made of concrete with $f_c^{\text{'}}=250k\frac{g}{c}{m}^2$ and bars with $f_y=4200k\frac{g}{c}{m}^2.$ For the calculation of the basic development lengths, consider #$3$ stirrups with two branches spaced $20$ cm apart. The load shown already includes load factors.
