STATISTICAL ANALYSIS OF STRUCTURAL PLATE MECHANICAL PROPERTIES FINAL REPORT Prepared for American Iron and Steel Institute Somchat Suwan Lance Manuel Karl H. Frank Department of Civil Engineering The University of Texas at Austin January 16, 2003 Acknowledgement This work was sponsored by the American Iron and Steel Institute (AISI) and was performed for the AISI Technical Committee on Plates. ii FORWARD This work was sponsored by the American Iron and Steel Institute (AISI) and was performed for the AISI Technical Committee on Plates. In 1974, AISI published a report dealing with variations found in hot-rolled steel plate. Entitled “The Variation of Product Analysis and Tensile Properties: Carbon Steel Plates and Wide Flange Shapes”, that report described the probability that tensile properties may differ among test locations within a plate other than the reported test location. In 1979 and again in 1989, AISI also published informational reports entitled “The Variations in Charpy V-Notch Impact Test Properties in Steel Plates”. In 1998, the AISI Technical Committee on Plates and Shapes included in their Workplans an item to update the aforementioned studies to reflect current mill practice. By the end of 1999, an acceptable proposal and format was developed with the University of Texas at Austin under the direction of Dr. Karl Frank, Department of Civil Engineering. Data was eventually
