Abstract

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