Hydraulic load definitions for use in Load and Resistance Factor Design (LRFD) analysis, including probabilistic load characterization, of 10 hydraulic steel structures : report number 1 Open
In the past, allowable stress design (ASD) was used to design steel structures. The allowable stresses used were determined from previous practice, with limited understanding of the reliability and risk performance provided by the structur…
