ABSTRACT
Many design codes in the world have now been revised to RBD Level I format. The limit state design (LSD),
PFM and LRFD are all included in this category of design verification format. The factors such as WTO/TBT agreement, near future establishment of the Structural Eurocodes, ISO documents (e.g. ISO2394
(ISO, 1998)) are all taking part in this movement (Honjo, 2006).
