Connecting to Eurocode 2: an investigation of reinforcement continuity connections for construction joints

Abstract

As the local market moves away from cheaper foreign labour and focusses on higher productivity, we should use every possible avenue and technique to ensure that this does not result in a ballooning in construction costs. One such way is to take advantage of the move away from BS 8110 to EN 1992-1-1; there are a number of subtle changes between the standards that can result in reduction of materials, providing we know where to look. The move has not been seamless as there are a number of omissions from Eurocode 2 that has caused confusion, for example, there are no longer any requirements for mechanical splices as this is deemed to fall outside the scope of a design standard. However, there are equally some new areas that are covered in much more detail and it is these we should focus on. This paper will look specifically at the design provisions of construction joint continuity and show how they can be utilised to both improve productivity and reduce the amount of steel required across the joint. This not only saves the contractor time and money due to lower material costs, but will also reduce the amount of embodied CO2 present in the structure as less steel will result in a “greener” solution. It will address the differences between current practices and new technologies that will enable smarter connections while staying firmly within the scope of MS EN 1992-1-1.
