For the reinforcement calculation of the frame beam, the calculation process is demonstrated by the reinforcement calculation of the first floor beam, and the reinforcement calculation of the remaining floors is listed in the form of a table.Taking the first floor frame beam as an example, the calculation process is shown as follows.According to the second chapter, the concrete grade of the beam is C30(fc=14.3kN/m, ft=1.43kN/m). Beam longitudinal reinforcement and stirrup are respectively
