A New Generation of Metallic Dissipaters for Low Damage Seismic Design of Structures
In this research, a new generation of metallic dissipaters has been proposed and experimentally validated. The dissipaters can be either in the shape of a brace or mini dissipater. The dissipaters offer advantages such as cost-efficiency, simple fabrication, replaceability, lightweight, ductility, strength, improved fatigue performance, redundancy during a large earthquake, option for self-centering, and compactness. The brace type dissipater can be used in buildings and bridges to absorb seismic energy. The mini dissipaters can be used in dissipative controlled rocking connections as external seismic energy absorbers. The paper presents a summary of existing metallic dissipaters. It discuss some common types followed by presenting the concepts for the innovative dissipaters. The concepts were experimentally validated using several prototypes which were tested under cyclic loading. Experimental testing showed stable and good performance of the dissipaters. None of the dissipaters showed any failure during the testing. The energy dissipation capability remained almost intact under cyclic loading. Furthermore, the mini dissipaters were tested in a precast bent with dissipative controlled rocking connections to validate implementation in a precast bridge substructure system.
