• Updated building code reflects changes made in 2002 and 2005, including:

2002 Code:

• A significant change in the reinforcement limits for flexural members and the manner in which the capacity reduction factors are calculated
• Changes in the capacity reduction factors for several design cases.
• Load factors have been adjusted to be consistent with those presented in ASCE 7 and IBC 2001

2005 Code:

• Changes in notations and section numbers.
• Change in the expressions for strength reduction or Ø factors for flexural members whose tensile steel strains fall in the transition range between tension-controlled and compression-controlled.
