Metallic dissipaters are displacement-activated elements that are used to absorb seismic energy in structures. The energy dissipation mechanism in metallic dissipaters can be axial, flexural, or shear. There are many types of metallic dissipaters developed over the years. One of these dissipaters, the U-shaped Flexural Plates (UFPs), are investigated in this paper. UFPs offer advantages such as simple fabrication, good energy dissipation, easy installation, good fatigue performance, replaceability, and cost-efficiency. UFPs have been implemented in actual structures in New Zealand. The most common material for fabricating UFPs has been “mild steel”. Despite the advantages, mild steel dissipaters are susceptible to corrosion and can be larger in size if higher capacity is intended. To overcome the issues of corrosion and size/capacity, two other materials, aluminum, and titanium alloy, are investigated for fabrication of UFPs. This paper presents investigation of UFPs made of mild steel, aluminum, and titanium alloy under quasi-static cyclic loads. The UFPs are experimentally tested and compared with each other. Furthermore, the advantages and disadvantages of each material are discussed. Experimental results showed that metallic dissipaters made of advanced materials such as titanium alloy can provide adequate performance while also offering the advantage for corrosion protection and higher capacity in a smaller package/size.
