Material and geometric properties of structural steel for use in design

摘要: This paper establishes an up-to-date measure of the variability material and geometric properties commercial quality structural steel. A comprehensive set measurements (over 7000 samples) was obtained collated. The large data sufficient to evaluate type probability distribution characterising variability. results provide detailed statistical evidence essential for reliability analyses needed underpin selection calibration new design rules steel components. reported are compared with measures assumed during Eurocode 3 (EC3) partial safety factors; it is shown that some these may safely be reduced.
