Abstrak/Abstract This paper discusses an experimental study investigating the behavior of the multidirectional box-shaped shearing damper (MBSD) proposed for a bridge structures application. The MBSD consisted of a box-shaped steel plate hot coil (SPHC) material with an effective dimension of 100 × 100 mm2 designed to dissipate earthquake excitation energy under the combined resultant forces from the longitudinal and transversal directions. The specimens varied in two different web slendernesses, i.e., 58.8 and 27.0. Furthermore, to investigate the different load direction effects, four different loading angles with respect to one of the web planes, i.e., 0°, 15°, 30°, and 45° to be implemented. The specimens were subjected to cyclic loading according to AISC/ANSI 341-22. In the experiment, the shear yield strength, ultimate state behavior, and energy dissipation achievement were evaluated. The results showed that MBSD could achieve shear strength and sufficient energy dissipation under different angles of loading directions, ranging from yielding to ultimate deformation state. The yielding and ultimate characteristics of MBSD were similar to those of an ordinary shear panel damper. A stockier web resulted in greater stability in stiffness after the yield point and less buckling of the web but also a slightly earlier strength degradation due to earlier fracture damage at the welded joint. Finally, the MBSD device had feasibility for application in bridge structure as a seismic device by considering appropriate strength and deformation capacity compatibility adjustments with the ultimate displacement limit of 0.11 rad drift angle. In addition, a recommendation for using a better elongation capacity steel material and less welding assembly will improve the behavior and seismic performance of the MBSD.
