The frame members are subjected to bending moments and shear forces caused by the story drift and relatively large axial forces caused by the damper force. The damper force and damper deformation have shifted phases, and the former is in phase with the frame story drift, which produces a phase difference between the moment and the axial force. In addition, the axial force can cause earlier yielding and possibly local buckling in the elements, but very few studies have investigated this problem. Because a detailed method of analyzing the connection elements, such as gusset plates and stiffeners, has not yet been established, buildings are constructed using a variety of designs, including many that are irrational and inadequate. Furthermore, stress concentrations at the gusset plate connecting the damper complicate the beam behavior. In this study, this was considered by analyzing data from beam–column–gusset plate subassembly tests. The subassembly test performed in this study employed a newly developed loading method alternating displacement control for story drift and force control for the damper force, the target value of which is calculated over a number of steps based on a hybrid scheme using a numerical model of the damper. Tests were conducted on 10 subassemblies consisting of a beam, a column, and a gusset plate, and the results were analyzed and discussed. When analyzing the data, two contributions containing the phases of the story drift and damper force were extracted from each of the forces shared by the steel beam and gusset plate and their corresponding strains. This paper discusses the results and their implication to the analysis and design of the members and connections in the damper. Some of the results are given below. ・
