The paper emphasizes the importance of reinforcing bar bond and anchorage problems in inelastic seismic analysis of reinforced concrete structures. The basic nature of the bond and anchorage problems is pointed out and relevant experiments carried out at the University of California, Berkeley, are described. The newly developed local bond stress-slip relationship (law) is commented on, and an analytical approach for the analysis of the deteriorating cyclic behavior of beam-column joints based on this law is discussed.
