Shear panel damper (SPD) has been implemented for supplementary energy dissipation in a wide range of structures. SPD is a kind of wide flange (WF) cross-section steel where the yield strength of the web (LY225) is much lower than the yield strength of the flanges (S355). The beneficial aspects of SPD are high energy dissipation capacity, sufficient ductility, and economical cost. Currently, the SPD is designed to work in one direction of deformation only. However, in real structures such as bridges or viaducts with lead rubber bearing (LRB) or high damping rubber bearing (HDRB) as seismic devices, both LRB and HDRB work in multi-direction of deformation in moving plane. This paper discusses a numerical analysis study using the finite element method (FEM) where the SPD can work at multi-directions of movement in the moving plane. In this study, the proposed multi-direction SPD model was simulated under one selected Crossing Web shape type. In realizing nonlinear material behavior, the metal plasticity material model with combined isotropic and kinematic hardening was adopted in the FEM model using ABAQUS software. Moreover, to measure structural ductility and energy dissipation, static cyclic loading was subjected to the SPD model in four different angle directions relative of the web plane axis, i.e., 0°, 15°, 30°, and 45°. The FEM simulation result found that the proposed SPD with load direction from 0° to 45° tends to show increased hysteresis parameters as the load direction angle increases. Furthermore, the SPD with a thickness of 8 mm at the load direction 0° resulting in larger resistance capacity associated with the displacement ductility. This multi-direction shear panel damper can generally be used and applied to bridge structures in particular. However, further research needs to observe the multi-direction SPD's behavior and the bridge structure together. |
