Abstract
AbstractDissipative structural behavior is a common feature of seismic resistant structures. In case of multi-story steel frame structures, the dissipative behavior can be controlled by providing a favorable plastic mechanism, which involves the formation of plastic hinges at predefined locations (e.g., beam ends and/or joints), while rest of the structure behaves essentially elastic. Ensuring the requirements for the development of the plastic mechanism can lead to high strength requirements for non-dissipative elements/components. A modern approach to fulfill these requirements and control the local/global hierarchy criteria is to combine two steel grades, i.e. high strength steels (HSS) in non-dissipative members/components and mild carbon steels (MCS) in dissipative members/components. Used in combination with replaceable dissipative elements, the solution of two steels, called dual-steel solution, is also effective in the recovery phase after an extreme loading, as it eases the retrofit intervention, i.e., creates a more robust and resilient environment. The study presented in the paper is a review of reference works on the practical application of dual-steel systems in multi-story steel building frames.KeywordsHigh strength steelDual-frame systemSeismic resistanceRobustness
