“…In addition, a steel plate device or fuse element that is accessible and easily replaceable is also a popular and inexpensive choice for energy dissipation because of its relatively sufficient ductility and effectiveness in the post-yield region. The damping, ductility, and reusability of steel have made it ideal for wide applications in energy dissipating devices (e.g., [4]). Particularly, the developments of self-centering rocking frames rely on the energy dissipation of steel shear plate fuses (e.g., [5], [6]).…”

Steel plate devices are broadly used in earthquake-resistant structures to provide energy dissipation. Understanding the cyclic response of these steel plate fuses requires comprehensive investigation of different fuse link design parameters. This goal can be achieved using finite element analysis. This paper presents the finite element modeling and sensitivity study of steel plate fuse links. Threedimensional finite element models are first developed and validated against past experimental tests. While validating the finite element models, several important components, including element type, material and meshing properties, boundary conditions, loading profile, and analysis method are discussed. The design of experiment (DOE) is then used to generate factor combinations for the parametric study. Seven potentially influential design factors related to the material or geometry of steel plate fuses are considered as input factors. Next, the cyclic response of fuses is assessed in terms of initial stiffness, yield strength, ultimate stiffness, effective damping, maximum load capacity, and ductility. The percentage contribution of significant design factors on each cyclic response variable is obtained.

“…Among various displacement-dependent dampers, metal damper has received the most attention. At present, researchers have developed many kinds of dampers, e.g., X-shaped stiffened steel plate damper [1], triangular stiffened steel plate damper [2], honeycomb steel plate damper [3], grooved steel plate damper [4], E-shaped steel damper [5], rod-and bar-type damper [6], and steel cushion [7,8].…”

The existing research on shock-absorbing steel bars is only limited to simply supported beam bridge. In order to expand the application of shock-absorbing steel bars to other fields, this paper develops a novel shock-absorbing steel bar with limit function, and it is suitable for continuous beam bridges. The structure and working mechanism of the shock-absorbing steel bar are analyzed. Three sets of specimens of the shock-absorbing steel bar are fabricated and then repeatedly loaded by the designed quasistatic loading device, in order to investigate their seismic performance parameters, including hysteresis curve, skeleton curve, and initial stiffness and equivalent viscous damping ratio. The results show that when the displacement of the specimen exceeds the initial gap, it enters the stage of energy dissipation and has a stable hysteresis curve and good fatigue resistance. Besides, the shock-absorbing device has a high initial stiffness and can provide stable bearing capacity after yielding. The equivalent viscous damping ratio reflects that the designed shock-absorbing steel bar has good energy dissipation capacity.

Abstract. Steel damper is a new damper which is composed of steel pipe and curved steel bar. Because of simple production and good economic performance, It has good application prospect in large span structure, such as grid and reticulated shell. On the base of introducing the basic structure of steel damper and considering nonlinear properties of material, finite element software ANSYS was used to establish the calculation model. Influence to damper performance with parameters variation is analyzed in this article, then seismic performance of spherical reticulated shell installed with damper is researched. The results of study show that the steel damper is good in seismic performance, and has good enhancement effect to seismic performance of large span structure, such as grid and reticulated.
