Abstract

The metallic dampers are one of the most widely used energy dissipation devices that can be used in building and non-building structures such as bridges. U-shaped metallic strips are among these tools. The effects of some parameters such as the number and arrangement of connection bolts on the cyclic behavior and energy dissipation capability during earthquake events will be evaluated in this study using nonlinear finite element method. According to the numerical results, simulation of the bolts, and their number and arrangements have significant effects in the resultant behavior in the transverse cyclic loading.
