AN EXPERIMENTAL STUDY ON THE STRESS DISTRIBUTION BETWEEN THE ATTACHMENTS AND SHEAR PLATE IN WEB-CLAMPED BEAM-TO-COLUMN CONNECTIONS

In this paper, pushover tests of half scale web-clamped type beam-to-column specimens in a T-configuration are conducted and compared to results from numerical simulations. Slip deformation in the bolted connection, which occurred in the tests, are not considered in the simulations. Through this comparison, the change of the internal force transfer in the attachments and shear plate due to the slip deformation in the bolted connection is investigated. Good agreement between the tests and simulations is obtained in the load - displacement relationship, load - joint rotation relationship, attachment axial strain distribution, and shear plate axial strain distribution. However, the simulations did not show good accuracy for the shear strain distribution in both attachments and shear plate, due to the effect of bolt slip.
