Grouted Pipe with Double Spirals for Precast Concrete Connections

Abstract:

This paper presents the pullout performance of grouted splice connections made with steel pipes and double spirals in connecting high tensile steel deformed bars. The parameters studied were the steel bar embedded lengths, grout strength and diameter of the pipe in influencing the tensile performance of the splice connections. A total of nine proposed grouted spiral connections with double spirals were tested under increasing axial tension until failure. The results indicated that the use of double spiral combined with grout strength of at least 60 N/mm2 and main steel bar embedded length of 10 times bar diameter could provide adequate bond strength to form a satisfactory precast connection system.
