Simplified Rules for the Evaluation of Moment Resisting Frames and Concentrically Braced Frames Seismic Performances
Recent earthquakes have highlighted the need for a prompt classification of the built heritage in terms of seismic vulnerability. The capacity of a structure can be assessed through nonlinear analysis, requiring onerous numerical procedures. Therefore, a simplified procedure for the evaluation of the seismic performance of steel Moment Resisting Frames (MRFs) and Concentrically Braced Frames (CBFs) not resorting to any static or dynamic non-linear analysis seems to be useful in everyday practise or the aftermath of a seismic event. The proposed performance-based method has been set up by a wide parametric analysis on several MRFs and CBFs. The design procedure has been developed according to 3 different approaches: the first is Theory of Plastic Mechanism Control (TPMC) ensuring the design of structures showing global collapse mechanism, the second is based on the Eurocode 8 requirements while the third is a design only for horizontal loads (not resorting to rules aimed at the mechanism control).
