Design and Analysis of Dual Ebfs Equipped With Prequalified Connections

Abstract

The aim of this work is to present the results of the design of Dual-Eccentrically Braced Frames (D-EBFs) according to the Theory of Plastic Mechanism Control. These frames are equipped with four prequalified connection typologies, analysed in the framework of the RFCS founded EqualJoints Plus research project. They are first designed disregarding the presence of the joints and after that accounting for it. The seismic performances of the structures are investigated by both pushover and non-linear dynamic analysis.

Design and Analysis of Freedam Frames: Comparison With Traditional Connections

“…In order to fill these gaps, the recently finished European research project EQUALJOINTS [34] was aimed at providing prequalification criteria of steel joints for the next version of UNI EN 1998-1 [32]. The following dissemination project EQUALJOINTS-PLUS [35]- [38], had the scope to promote the valorisation and dissemination of the technical knowledge and the design tools developed within the EQUALJOINTS project. The goal is to reach a wider and easier use of dissipative beam-to-column connections in steel seismic resist-ing systems in Europe.…”

Seismic Behavior of the Removable Links in Eccentrically Braced Frames with Semirigid Connections

“…is topic has also been faced by the recently accomplished EQUALJOINTS Plus Dissemination project, where many EBFs structures have been modeled and analyzed accounting for prequalified semirigid connections. e results of this project, mainly for what regards EBFs, are reported in [3]. EBFs can improve the lateral stiffness of the structure and have a certain ductility and energy dissipation capacity.…”
