Jefferson and B.I.G. Barr University of Wales Cardiff, Cardiff Three draft RILEM recommendations for evaluating the fracture characteristics of concrete are currently under consideration. The main objective of reported is to the advantages of all three proposed methods a single testing procedure by combining the testing arrangements for the Gp test with the Two Parameter Method (TPM) applying them to compact centrally notched cylinder specimens subjected to three point bending. This compact geometry is also suitable size effect studies. Numerical and experimental work carried out to validate the proposed procedure is reported. Three sizes have been tested a closed loop set analysis been carried out using authors' three contains a concrete model. Good agreement and analytical was achieved. draft RILEM recommendations for evaluating the fracture properties concrete are currently consideration, namely the GF test, 985), the Two-Parameter model (TPM), RILEM 990a) and the · (SEL ), 990b ). All three recommended test methods use beam test specimens subjected to three-point bending. three test methods have their respective advantages and disadvantages. The main objective of the work reported here is to combine the advantages of .l ......... , ... .l.l../U.IJ into a single which is suitable for obtaining fracture from cores from existing structures as well as new concrete disadvantage three draft recommendations is that tests out on rectangular beam specimens.
