This study aims at evaluating the capacity of steel moment frame (MRF) structures at collapse limit state designed according to the current version and next release of Eurocode 8. To this purpose, the framework of performance-based earthquake engineering according to PEER is adopted. The collapse intensity and subsequently the mean annual rate of collapse are computed as an index of comparison. The structural assessment is carried out by means of nonlinear static and dynamic analyses on 2D models developed using “OpenSees”. The results show that the incoming version of the EC8 allows exploiting the inherent ductility of the structure, while having the same collapse risk as the frame designed in accordance with the current version of EC8.

Abstract

This study aims at evaluating the capacity of steel moment frame (MRF) structures at collapse limit state designed according to the current version and next release of Eurocode 8. To this purpose, the framework of performance-based earthquake engineering according to PEER is adopted. The collapse intensity and subsequently the mean annual rate of collapse are computed as an index of comparison. The structural assessment is carried out by means of nonlinear static and dynamic analyses on 2D models developed using “OpenSees”. The results show that the incoming version of the EC8 allows exploiting the inherent ductility of the structure, while having the same collapse risk as the frame designed in accordance with the current version of EC8.
