The application of linear fracture mechanics to the crack propagation load of pre-cracked concrete specimens is shown to depend upon the size of the specimen. The results of twenty-four tests on cracked beams with depths ranging from 3-in to 15-in (75-mm to 375-mm) are presented in support of this conclusion. /AUTHOR/
