Innovative Structural Fuse Systems for Various Prototype Applications

To resist the imposed lateral forces on the structures, hysteric dampers are developed from steel plates and strategically implemented within various structural applications. The structural shear dampers are recently used to alleviate damages, while remaining members remain intact and undamaged. The practical use of the innovative dampers in structural applications is investigat-ed in this study. For this purpose, the design methodology for as set of innovative shear damp-ers is initially elaborated, for which the dampers are designed considering the governing shear and flexural ductile limit states, while the brittle buckling limit state is prevented. Subsequently, the finite element modeling methodology is verified and compared to laboratory tests for computationally analyzing various shapes of the shear damper in structural applications. Three major general prototype structures are established, and shear dampers are designed to be in-corporated in prototype applications. For each of the proposed applications, at least six different shapes of shear dampers are designed and subsequently compared with conventional systems. The results determined that the use of innovative shear dampers could effectively reduce de-mand forces on the boundary elements more than 40% in average, while the strength and the stiffness alter within less than 5% margin of difference.
