Abstract

This paper presents the results of an experimental program conducted in order to investigate the behavior of Type-I beam-column Joints, where the beam was subjected to shear stresses due to combined effect of shear force and torsional moment (beam eccentric loading). Four beam-column joint specimens were constructed and tested up to failure in order to better understand the complicated behaviour due to combined loading transmitted from the beam to the column. The studied parameters were the configuration of beam side and secondary reinforcement and the existence of the joint reinforcing stirrups. Generally, the shear failure at the beam zone or at the joint panel was noticed to be the governing mode of failure for all tested specimens. The test results shed the light on the importance of longitudinal side reinforcing steel configuration, the inadequate embedded length of the beam side and secondary steel into the joint panel including stirrups led to decrease the beam capacity but it kept the failure away from the joint panel.
