The transverse reinforcement of the beam-column joint is a rectangular closed stirrup, which must meet the requirements for the amount of stirrup around the column in the special earthquake resistance regulations. The formula is as follows. As shown in the figure, if the column bears an axial force of 0.4Ag fc', how should the distance between the transverse steel bars at the inner column section of the beam-column joint meet the specification requirements. known conditions: fc'= 280 kgf/cm^2, D25 steel bars (db = 2.54 cm, Ab = 5.07 cm^2, fy=4200 kgf/cm^2), D13 steel bars (db = 1.27 cm, Ab = 1.27 cm^2, fy = 4200 kgf/cm^2).

The transverse reinforcement of the beam-column joint is a
rectangular closed stirrup, which must meet the requirements for the
amount of stirrup around the column in the special earthquake
resistance regulations. The formula is as follows. As shown in the
figure, if the column bears an axial force of 0.4Ag fc', how should the
distance between the transverse steel bars at the inner column
section of the beam-column joint meet the specification
requirements.
known conditions:
fc'= 280 kgf/cm^2,
D25 steel bars (db = 2.54 cm, Ab = 5.07 cm^2, fy=4200 kgf/cm^2),
D13 steel bars (db = 1.27 cm, Ab = 1.27 cm^2, fy = 4200 kgf/cm^2).
