Development of Self-Stabilizing Links for Eccentrically Braced Frames
This paper highlights aspects of the development of self-stabilizing links having tubular cross-sections for use in eccentrically braced frames (EBF’s). EBF’s utilizing this type of link could be used in bridge piers or other applications where lateral bracing to prevent lateral torsional buckling is difficult to provide. The development of design recommendations for these types of links consis...
متن کاملTubular Links for Eccentrically Braced Frames. II: Experimental Verification
This paper describes the results of an experimental study to verify proposed design requirements for eccentrically braced frame links with hollow rectangular i.e., tubular cross sections. Twelve primary link specimens and two supplementary links that have different end connections are tested. Three cross sections and four normalized link lengths are considered. Two of the cross sections have we...
متن کاملA New Approach to Predict Cyclic Response and Fracture of Shear Links and Eccentrically Braced Frames
In eccentrically braced frames (EBFs) subjected to large lateral demands, inelastic actions are mostly concentrated in shear links. The links vary in size and, when employed in frames, are known to be subjected to combined tension/compression and shear stress states that influence their strength, low-cycle fatigue behavior, and fracture characteristics. Despite their significance as the main en...
متن کاملDual-Steel Eccentrically Braced Frames with Bolted Links – Simulation of Safe Removal Process
Current seismic design philosophy is based on dissipative structural response, which implicitly accepts damage to the main structure and significant economic losses. Repair of the structure is often impeded by the permanent (residual) drifts of the structure. The proposed research aims at reducing the repair costs and downtime of a structure hit by an earthquake, and consequently more rational ...
متن کاملSeismic Yield Displacement Profile in Steel Eccentrically Braced Frames
Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...
