Abstract
The performance of four half-scale interior joints with respect to joint shear stress and beam bar anchorage lengths is described. The main variable in the tests was the column depth, which was changed to produce anchorage lengths of 16, 20, 24, and 28 bar diameters. The half-scale specimens were subjected to a large number of cycles in the elastic and inelastic range. Cycling in the elastic range indicated that severe bond deterioration can occur even at this level if the anchor age is short. Cycling in the inelastic range indicated an interaction between anchorage length and joint shear stress level. The tests indi cate that the current ASCE-ACI Committee 352 recommendations are adequate to provide ductility and energy dissipation capacity. The latter, however, depends strongly on the anchorage length as the de terioration in hysteretic behavior can be large if short anchorages are used.
