Splitting tension tests to determine concrete fracture parameters by peak-load method

An experimental program confirms that the peak-fond method can be successfully applied to splitting tension tests to determine fracture parameters K-Ic(S) and CTODc of the two-parameter fracture model from the measured peak loads. The peak-load method requires distinct specimens. If is found that a hole drilled at the axis of splitting tension cylinder can largely expand the specimen distinction. Combination of tests on splitting tension cylinders with and without a hole raises the reliability of the K-Ic(S) and CTODc values determined by the peak-fond method. (C) 1997 Elsevier Science Ltd.
