Performance of Powder Actuated Fasteners as Direct Fastenings in Steel Fibre Reinforced Concrete
Currently, we expect a wider development of modern concrete mixes in the construction industry, such as concretes with alternative cement types and binders, recycled aggregates but also concretes with dispersed fibre reinforcement, in order to accelerate our efforts to reduce greenhouse gas emissions and to increase the service lives of built assets. In fact, steel fibre reinforced concrete is now gaining in applications such as industrial floors, slabs, and tunnels and it is being introduced to the next generation of Eurocode 2. A well-established fastening method is direct fastening by use of powder actuated fasteners (PAF), which bring along several benefits in terms of speed and ease of site work. However, due to the significant variability in the installation and load-bearing performance of such fasteners, particular focus needs to be diverted to the reliability characteristics and a redundancy-based design approach. The objective of the presented study is to provide fundamental engineering concepts for direct fastenings and to share and discuss the first worldwide experimental results on the performance of PAF in steel fibre reinforced concrete. The conclusions enable a comparative assessment for different fastener types and fibre types and content allowing for useful conclusions for the design and they provide a substantial reference for future research and applications.
