Observations on the structural design and analysis of a piping system
The structural design/analysis of a gas exhaust system at a nuclear fuel facility is used to investigate some aspects of current piping design procedures. Specifically the effect of using various stress measures including ASME Boiler Pressure Vessel (B PV) Code formulas is evaluated. It is found that large differences in local maximum stress values may be calculated depending on the stress criterion used. However, when the global stress maxima for the entire system are compared the differences are much smaller, being nevertheless, for some load combinations, of the order of 50 percent. The effect of using an equivalent static method (ESM) analysis is also evaluated by comparing its results with those obtained from a response spectrum method (RSM) analysis. It is shown that a spectrum amplification factor (equivalent static coefficient greater than unity) of at least 1.32 must be used in the current application of the ESM analysis in order to obtain results which are conservative in all aspects relative to the RMS analysis. However, it appears that an adequate design would be obtained from the ESM approach even without the use of a spectrum amplification factor. 7 refs., 4 figs., 7 tabs.
