The "Allowable Stress Design Method" has long been used for the design of cold-formed steel structural members. The "Load and Resistance Factor Design Method" has recently been developed from a research project sponsored by American Iron and Steel Institute. In this method, separate load and resistance factors are applied to specified loads and nominal resistance to ensure that the probability of reaching a limit state is acceptably small. These factors reflect. the uncertainties of analysis, design, loading, material properties and fabrication. They are derived on the basis of the first order probabilistic methodology as used for the development of the …

Allowable Stress Design is the current method used to design cold-formed steel structural members and connections. In this design approach, factors of safety are used to compute the allowable design stresses which are compared to the actual maximum stresses that will occur in the member during the life of the structure. In recent years, the Load and Resistance Factor Design (LRFD) method has been developed for the design of hot-rolled steel shapes and the design of cold-formed steel structural members. This method is based on probabilistic and statistical techniques to account for the many uncertainties involved with the actual design. …

I. INTRODUCTION A. GENERAL In the past few years, a dramatic increase in the use of high strength sheet steels in automobiles has been brought about by the demand for improved fuel economy and safety of motor vehicles. Many of the automotive structural components, which are made of high strength sheet. steels, consists either partially or totally of curved elements. Therefore, it was decided to include an investigation into the structural behavior of curved elements as a part of a research project entitled, "Structural Design of Automotive Structural Components Using High Strength Sheet Steels." The research project began in early …

Comparison And Evaluation Of Web Crippling Prediction Formulas, Monique Bakker, Teoman Peköz

Since the use of end and load stiffeners is frequently impractical in thin-walled cold-formed steel construction, the webs of beams a.nd deck oay cripple due to the high local intensity of the load or reaction. In this report three different web crippling prediction formulations are compared with experimental results from five different sources. It is found that these web crippling formulas show considera.ble differences and do not give satisfactory results consistently.
