Abstract

Double tee connection in a beam column joint is a semi rigid connection in which two T stubs are bolted to the members. Use of these T stubs will be beneficial in seismic prone areas as they exhibit higher initial stiffness and ultimate moment capacity. Since plastic deformations are limited only in T stub, the connection can be easily repaired by replacing it after a destructive earthquake. The thickness and shape of T stub components have significant roles in enhancing the moment carrying capacity and they can influence the failure mode also. This study is mainly intended to investigate the performance of double tee connection by adding T stub rib stiffener and shear tab into the beam column joint. Parameters such as T flange thickness, T stem thickness and T stem shape are considered in the analysis.

Keywords: T stub, rib stiffener, shear tab, ultimate moment, failure mode
