I have the following letter from Professor Karl Frank of the University of Texas at Austin. Suggest readers distribute this survey form to anybody who can help. Or let me so I can contact them. Posted by Y. Henry Huang, Los Angeles County Public Works Department November 11, 1996 The second phase of the SAC Steel Project, a joint venture between Structural Engineers Association of California, Applied Technology Council, and California Universities for Research in Earthquake Engineering which is funded by FEMA, has as one of its tasks the determination of the strength of rolled structural shapes. I am the topical team leader for this investigation. The significance of changes in the production of structural shapes from integrated mills to scrap based electric furnace producers using continuous casting, The marketing of dual grade material, and The predominance of grade 50 steel upon the distribution of steel strength is unknown. Previous work was restricted to A7 and A36 steel produced using older steel making processes. An experimental study to determine the relationship between mill test values and laboratory test results will be started shortly. The purpose of this study is to relate the data available from surveys of current mill tests to member strength under dynamic and static loading. I ask for your help in this effort. We need as much data as we can gather to include in this study. I have enclosed a form for you to report any data you may have concerning The measured tension strength and charpy V notch properties of rolled shapes. Data from tests performed in the last 30 years is needed. Measured steel properties form research specimens, consulting investigations, or other sources are needed. If the data is available in another format, please just send a copy of the data. I realize that not all The data requested on the form may be available. please include what data you have. All data will be kept confidential, however your participation in the survey will be acknowledged unless you wish to remain anonymous. Please call me if you have any questions concerning this survey. Please pass this letter and data form on to your colleaaues who may have additional data. Thank you for participating in this effort.
