Abstract:The concept of robustness of structures and its importance for preventing collapse against strong earthquake are firstly introduced. Then the influence aspects to the robustness of seismic structures, including structural systems, failure modes, strength and ductility of structure, and redundancy elements, are discussed. The approaches to increase the robustness of seismic structures are suggested.

Keywords:seismic structure; robustness; structure system; integrity; failure mode; strength; ductility; redundancy elements
