Abstract: Post-installed rebar connections are increasingly used in practice. Several different systems are on the market. To investigate the bond behavior of these systems pullout tests with single rebars and tests with splices were performed. Cast-in-place and post-installed rebars using different systems were tested side-by-side. To investigate the influence of different bond stiffness on transverse cracking three dimensional finite element simulations of splices with different splice length were done.
The Investigations show that the bond stiffness and bond strength influences the splice strength and the crack formation along the lap length. When the used systems to postinstall rebars provide comparable bond stiffness and no lower bond strength than cast-inplace rebars, design can be done according to the codes for reinforced concrete. Exceptions have to e made at minimum concrete cover, minimum embedment length and at elevated temperature.
