Abstract: This paper provides general overview on the design principles of steel structures in Seismic Zones. In particular, seismic design of multi-storey steel structures using limit states (ultimate, serviceability and damageability) and performance based design approach is firstly discussed and the importance of steel structures is consequently highlighted; then, general concepts to be incorporated in the structural design are provided. The well-known adopted lateral load resisting systems (moment resisting and braced frames) are also criticized to highlight the pros and cons of each system. The concept of dissipative and non-dissipative Zones is given for each lateral load resisting system; and therefore aims to give useful information for the engineers and technicians involved in the design of steel structures in the seismic zones.Abstract: This paper provides general overview on the design principles of steel structures in Seismic Zones.
