Characterization of the Material Properties of Rolled Sections 

Principal Investigator: Karl Frank 
University of Texas at Austin 

    This task is intended as the initial effort to better characterize the basic material properties needed to develop connection and element design procedures. The Principal Investigator for this work will be in close liaison with AISC, SSPC and other steel industry representatives. Specific objectives of this project include the following: 

1. To determine the relationship between mill test tension tests and the dynamic and static strength of rolled sections. 

2. To characterize the complete stress-strain behavior of the steel that are presently being produced. 

3. To better understand the Charpy V Notch (CVN) toughness levels of various sections, and the potential for variation of this value across the cross section. 

4. To investigate the properties of the rolled section in the region of the web to flange junction ("k" region). 

5. To better understand the complete chemical composition of structural steels.
