A STUDY OF THE IN SITU VARIABILITY OF CONCRETE USING THE PULL-OFF METHOD

The allowance for concrete variability in reinforced concrete design to specifications CP 110 and BS 8110 is discussed, and previous research is briefly reviewed. This paper describes a programme of partially destructive in situ tests on a multi-storey car park to determine the concrete strengths and variability in that structure and includes a detailed analysis of the results. This information is then used to assess the adequacy of the partial safety factor for concrete strength at the ultimate limit state. (Author/TRRL)
