Assessment of influence parameters on joint shear behavior in RC beam-column connections subjected to seismic lateral loading

Abstract

An extensive database has been constructed of reinforced concrete (RC) beamcolumn connection test specimens subjected to quasi-static cyclic lateral loading (with at least a minimum amount of joint transverse reinforcement necessary for proper joint confinement). The aims were to identify key points of the overall behavior and to investigate governing influence parameters at key points of the local behavior. Examined parameters for local behavior were grouped by material property, joint panel geometry, reinforcement confinement, column axial load, and reinforcement bond condition. Concrete cracking and yielding of joint transverse or longitudinal beam reinforcement triggered the most distinct changes in stiffness for both overall and local behavior up to the point of initiation of joint shear failure (maximum story shear). Although the influence parameters on joint shear behavior were somewhat different according to connection type and failure mode, the most common dominant parameter was concrete compressive strength. In interior joints, joint shear strength was also influenced by whether bond demands on not-yielded beam and/or column reinforcement reached an upper limit leading to a reduction in average bond stresses within the joint panel.
