Responding to the demand for high strength and high ductility steels, high strength steel with a low yield ratio is recently produced and becomes available in the market. This paper outlines the guideline of structural design to utilize thenew high strength steel, 60 kgflmm.2 class high performance steel, in building structures. The guideline was developed by an ad hoc committee where research works have been done intensively on some important items in stability design and connection design. Along the guide, the new steel can be used as a steel material in the current design practice.
