Abstract (english)

This paper summarizes the experimental campaign carried out for the development of a new steel energy
dissipative device named Slit Dampers (SDs) designed for earthquake protection of structures. SDs consist in
shear steel plates with appropriately shaped cut-out portions of material for allowing the maximum spread of
plastic deformation along the device and then maximizing the hysteretic dissipative behavior. A total of eightytwo steel shear plates with different openings and thicknesses are tested to investigate their behavior under cyclic
pseudo-static loading. Six types of steel shear plates are studied, including the SD with narrow slits that divide
the plate into rectangular links, and the butterfly fuse with a diamond-shaped opening that creates butterfly shape
links in the plate. Other varying test parameters are loading rate, material strength, and the number of in-parallel
damper elements. It is expected that the proposed model can be successfully used to predict the behavior of
dampers in real-world applications.
