case of the same conditions, B-1 and B-2 had almost no pre-cracking and little additional difference in deflection; B-4 had the largest degree of pre-cracking and the minimum additional deflection; B-3 had a medium degree of pre-cracking, and a medium additional defection (smaller than B-4 yet greater than B-1 and B-2).
