Type of concrete:
(Note: For normalweight concrete, enter 1 | For lightweight concrete, enter 2)

Specified compressive strength of concrete(MPa):

Condition of epoxy:
(Note: For epoxy-coated or zinc and epoxy dual-coated reinforcement, enter 1 | For uncoated or zinc-coated (galvanized) reinforcement, enter 2)

Bend degree:
(Note: Enter 90 or 180)

Diameter of longitudinal tension steel(mm):

Specified yield strength of longitudinal tension steel(MPa):

Confining reinforcement:
(Note: For No. 36 and smaller bars with total cross-sectional area of ties or stirrups confining hooked bars greater than or equal to 40 percent of total cross-sectional area of hooked or headed bars being developed at a critical section or minimum center-to-center spacing of hooked bars greater than or equal to 6 times diameter of hooked bars, enter 1 | For other confining reinforcement, enter 2)

Location of longitudinal tension steel:
(Note: For No. 36 and smaller diameter hooked bars terminating inside column core with side cover normal to plane of hook greater than or equal to 65 mm, enter 1 | For No. 36 and smaller diameter hooked bars that with side cover normal to plane of hook greater than or equal to 6 times longitudinal tension steel, enter 2 | For other location of longitudinal tension steel, enter 3)
