  • Reduction of Development Length ok? -

    31.03.2009· Thanks for the support, NS4U and for the practical example you provided. Even though a reduction of 50% (NS4U's example with area of steel) and a reduction of 43% (NS4U's example with steel capacities) are reasonably close, they are not exactly the same, and the variance may be even more if the dimensions are different.

  • Specifying ratio of yield to ultimate tensile

    There may further be a requirement for pipes with σ γ /UTS ratios somewhat below typical values of around 0.9, particularly when the steel pipe could be subjected to significant strains during handling, for example if the pipe was to be reeled or likely to be subject to land slip or earthquake in service. In this case, it is required that the pipe is able to withstand appreciable plastic
