Abstract : This report summarizes the results of a series of tests conducted on the behavior of high yield strength structural steels. The results of the tests on sizes of large restrained welded specimens indicated that the width and height of this type of specimen apparently had little or no effect on the transition temperature. The results of the tests performed on notched plate specimens showed that the transition temperatures determined by tests of the two sizes of this type of specimen were in good agreement with each other, but that the transition temperatures as determined by notched plate tests were considerably lower than those obtained with large restrained welded specimen tests. Tension tests of simple welded flat plate specimens indicated that the transition temperatures of the steels were not materially affected by the introduction of a single longitudinal weld along the loading axis or by the presence of two intersecting welds at the center of the unnotched plate specimen.
