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

Confining reinforcement:
(Note: For reinforcement enclosed within a spiral, enter 1 | For reinforcement enclosed within a circular continuously wound tie with a diameter greater than or equal to 6 mm and pitch 100 mm, enter 2 | For reinforcement enclosed within No. 13 bar or MD130 wire ties spaced less than or equal to 100 mm on center, enter 3 | For reinforcement enclosed within hoops (having seismic hooks at both ends) spaced less than or equal to 100 mm on center, enter 4 | For other confining reinforcement, enter 5)
