It is a well known fact that the beam-to-column conection of steel structure, that is, so called panel zone, takes much deformation when it suffers severe earthquake load, etc., because it consists of this wed plate. For that sake, we usually take the shear deformation of panel zone into account in case of the design of multi-story building, or stiffen it by another steel plate to prevent the deformation. On the other hand, there is another problem that panel zone is surounded by many weld lines and has much residual stresses by welding. It is clarified that the strength and ductility of steel structure would be much influenced by residual stresses, for instance, the instability of column and plate and so on. In this paper, the authors made clear the distribution pattern of residual stresses in panel zone and the co-relation between the shear strength and residual stresses by the experiment of beam-to-column specimen.
