Grouted sleeve connections used in precast reinforced concrete construction - Experimental investigation of a column-to-column joint

摘要

The results of an experimental campaign concerning full-scale tests on precast reinforced concrete column-to-column connections made with grouted sleeve splices are presented. The precast column units had a square cross-section with the side of 500 mm. Eight 20 mm-diameter bars protruding from one unit were grouted into corrugated steel sleeves encased in the other unit. The column-to-column connections were subjected to three monotonic tests (axial tension and four-point bending with and without axial compression) and to two cyclic tests (four-point bending and shear).
