“…However, as the number increased to four, the bond capacity of the splice reduced from 147.7 kN to 144.6 kN. It is likely that the interlocking mechanism in the elastic segment, which cause bond reduction in this region ( Sayadi et al 2014( Sayadi et al 2015. For this reason, it can be concluded that providing interlocking in the elastic region of sleeve is not a reasonable way to enhance bond capacity.…”

Abstract.A new type of grouting coupler for rebar splicing was fabricated with common seamless steel pipe by cold rolling technique. Seven splice specimens were prepared with the sleeve and tested under pullout load. The test results have shown that given a proper embedded length, the specimens provided good behaviour of which the ultimate tension load exceeded the required loading capacity specified in ACI318 and JGJ107. The pullout behavior of grout-filled pipe splice are influenced by the inner cavity structure of the sleeve.

“…Based on the theories illustrated in previous studies [3][4][5][6][7], many grouted splices in which bars were spliced in line were invented [1,[8][9][10][11][12][13][14][15]. However, the construction of the sleeve was rather complicated, and manufacturing was relatively expensive.…”

Experimental study of grouted sleeve lapping connector under tensile loadThe performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for calculating the average lapping bond stress and critical lap length. Eksperimentalno ispitivanje injektiranog prstenastog preklopnog spoja uslijed vlačnog opterećenja U radu se analizira izvođenje injektiranog prstenastog spoja koji je korišten za spajanje armaturnih šipki u predgotovljenim betonskim konstrukcijama. Ispitana su ukupno 63 uzorka, koja su se razlikovala po promjeru šipki i duljini spoja uslijed vlačnog opterećenja. Istraživanjem je obuhvaćena vrsta sloma, granična vrijednost vlačne čvrstoće te dijagram opterećenja i progiba uzorka. Preporučena su dva izraza za proračun prosječnog naprezanja prstenastog spoja i kritične duljine spoja.Ključne riječi: predgotovljena betonska konstrukcija, ovijanje prstenastog spoja, prokliznuće prianjanja, duljina preklopa

“…There could be other forces acting on the connection. Hence, experimental studies were conducted on the precast concrete frames with the connections of beam-to-beam (Aldin Hosseini et al 2015;Sayadi et al 2014), column-to-beam (Ameli et al 2015;Kim 2000), column-to-column (Tullini and Minghini 2016), wall-to-wall (Soudki et al 1995;Zhu and Guo 2016) and column-to-foundation (Haber et al 2014;Belleri and Riva 2012) to determine the structural performance.…”

This paper presents an experimental study of a new grouted splice connection for wall panels, called Welded Bar Sleeve (WBS). The connections were made from steel pipes and tested with incremental tensile, shear and flexural loads until failure. The aim is to determine the behaviour of the connection under the three load cases. For this, the connections are evaluated in terms of the load-displacement responses, ultimate capacities, ductility responses and some feasibility assessment criteria. WBS was found to provide sufficient strength at the bar embedded length of 8, 8 and 11 times the bar diameter under tensile, shear and flexural loads, respectively. It is effective under tension, but could only service up to 1/3 of its ultimate shear capacity. Flexural load is the most critical load case for the connection. For this, further enhancements are required when subjected to shear and flexural loads.
