in this paper the effect of cold joint has been discussed for two RC Beam-Column Connections. Specimen 1was poured monolithically whereas, construction joint in specimen 2 at bottom and top column was provided accordingto section 3.2.2.2, ACI 224.3R-95. Both specimens were tested through quasi static cyclic loading under displacementcontrolled condition, and the effect of cold joint was investigated. It was concluded that due to construction joint inconnections the maximum load carrying capacity decreases up to 39%. In addition, the strength degradation was more inspecimen having construction joint in column. Similarly the stiffness degradation decreases up to 50% due constructionjoint. It was also observed that specimen having construction joint shows overall strength lost at 1.5% while specimenhaving no construction joint was maintain their strength up to 3% drift.
