The behavior of interior beam-column joints unders seismic actions is examined in detail. The exisitance of two shear resisting mechanisms, one involving joint shear einforcement and the other a linear concrete strut, is postulated and the effects of reversed cyclic loading on these mechanisms, in both elastic and inelastic range of response, are discussed. Simple analytical models of behavior are presented. The determental effects of yield penetration into a joint upon longitudinal bar anchorage are discussed, and methods to overcome these effects are proposed.
