| Research Abstract |
In general, standard beam-to-column connection panels are commonly adopted in which both the right and left beams connected to a column share identical beam depth and flange position. However, due to functional requirements and with the aim of reducing the weight of the steel frame, connections were adopted in which the beams on either side of the columns have a different beam depth and flange position. Such panels are called offset panels. These panels exhibit several collapse mechanisms. In this paper, an equation is proposed that calculates yield strength during the formation of various collapse mechanisms based on the elastic analytical method, and at the same time an examination using parametric calculations is made of the effect of various parameters on panel yield strength. The research results thus obtained have clarified the collapse mechanisms to be examined at the design stage depending on the sectional configuration of the columns and panels.
