Seismic Details of Reinforced Concrete Structures of Limited Ductility in New Zealand Standard

As the level of earthquake intensity in Korea is considered to be moderate, some structures or structural elements may be subjected to the reduced ductility demand, in contrast to the structures in high seismicity, due to the large inherent strength induced by gravity loads. New Zealand Standard(NZS) deals with there structures within the category of structures of limited ductility. This paper briefly reviews the applicability of the code, regarding limited ductility, for frame strucures which are commonly used as the office building structural system. The difference of the loading condition is considered. Details of the plastic hinge region are compared between NZS and Korean standard.
