Short Headed Fastenings in Concrete Structures – Theoretical and Experimental Investigation

The precast concrete structures are very popular for many construction designers. The appropriate design and performance of structural joints are essential preconditions for durability and effectiveness of this type of structures. Headed fastenings made of rebar steel appertain currently to the attractive solution for creating compact structural joints. The resistance of this type of anchors can be increased by using supplementary steel reinforcement. Our research and studies, focused on headed fastening and supplementary reinforcement, are briefly described. The experimental research is then discussed in the paper.
