摘要：
Characterized by large plastic deformation and energy-dissipation capacity, low-yield-strength steel shear panel dampers (LYSPDs) are widely used as energy-dissipating members in seismic engineering. However, the effect of welding on the properties of LYSPDs remains unclear. Hence, in this study, we investigated the matching performance between low-yield-strength steel (LYS) and two different welding materials. Subsequently, the quality of welding between LYS and dissimilar metals was investigated. Furthermore, the fracture characteristics of the welding seam of LYS under large plastic deformation were explored. Finally, the welding performance of LYSPDs under large plastic deformation was verified under cyclic loading. The results of this study are significant in terms of the effect of welding on the properties of LYSPDs.
