| description | The earthquake has become a problem in many countries in the world, especially triggering loss of infrastructure due to damage or collapse. In the bridge structure, the critical part that provokes structural damage or collapse occurrence is the plastic hinge of the pier. The main problem is the pier of the bridge has limited ductility, so they are not able to resist a significant earthquake. The application of a passive energy dissipation device is one solution alternative to solve the problem, i.e., shear panel damper (SPD). Currently, SPD is designed to damp seismic forces only in one direction. However, in the real case, the seismic force that works on SPD installed in bridge structure works in multi-direction. This paper discusses an analytical study of two-directional finned tubular shear panel damper (FTSPD) as energy dissipation and resistance devices in the pier of bridges. The beneficial aspects of FTSPD are high energy dissipation capacity, high strength, sufficient ductility, and economical cost. In this study, FTSPD is designed into four models, namely, without fins, four vertical fins, six vertical fins, and eight vertical fins. For this purpose, finite element software (ABAQUS) was conducted to investigate the energy dissipation capacity, damping capacity, ductility, and strength of FTSPD. The main component of the models is tubular steel, which uses low-yield strength LY225, but its plates and fins using S355. In realizing non-linear material behavior, metal plasticity with combined isotropic and kinematic hardening was adopted. Moreover, to calculate the nominal energy dissipation and damping capacity of each model, forty-cyclic loadings on the top of FTSPD were used. The FEM simulation result found that inelastic buckling occurred in TSPD, which not uses fins. On the other hand, FTSPD, which employs more fins, could achieve more high dissipation energy and ductility. This study shows that the implementation of fins can delay buckling occurrence and improve energy dissipation capacity, damping capacity, and ductility of FTSPD. With those achievements of FTSPD, the structural bridge damage under severe earthquake excitation expected could be reduced by implementing FTSPD on a bridge structure. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
