Seismic behaviour of eccentrically braced frames

Influence of the link overstrength factor on the seismic behaviour of eccentrically braced frames

“…This choice has been guided by the results of some recent numerical tests [11] where the advantages of such sections have been pointed out with reference to the link lengths considered in this paper. The same study has also highlighted that, according to EC8 and EC3, all HE B sections have sufficient local ductility for use in highductility structures.…”

On the selection by MCDM methods of the optimal system for seismic retrofitting and vertical addition of existing buildings

“…Instead, in the second test, both the shear failure of link-to-diagonal connection bolts and a relatively small plastic deformation of links, thus indicating link over-strength larger than expected, were recorded. Finally, in the third test, as on the basis of previous studies [10], a significant plastic deformation of links was occurred, but once again failure with the (predominantly) shear rupture of link-to-diagonals connection bolts was observed. The Later on, the research group of the University of Basilicata, based on the results of previous studies [11], proved the effectiveness of NiTi SMA-based bracings for retrofitting purposes.…”

A Semi-Analytical Model for Dissipative Shear Links: Experimental Tests and Numerical Analyses

“…Nonlinear modelling approaches, spreading from simple concentrated plasticity models [10] to distributed fibre elements and, finally, to complex continuum models [11], shall be properly defined depending on the purpose of the analysis, being their accuracy strongly dependent on the computational burden.…”
