Abstract
In order to design H-section column-to-H-section beam connection with split-T stubs, out-of-plane deformation of flange plate of H-section column should be considered, which causes semi-rigidity of the connection, especially in the connection detail without transverse stiffener. Estimation of yield and ultimate strengths of the connection is derived from plastic analysis by assuming yield and ultimate mechanisms concerning out-of-plane deformation of the flange plate of H-section column and stretch of high-strength bolts. The assumed mechanisms and analytical estimation of strength of the connection are verified by comparing with the results of experimental studies by tensile tests of the connection.
