自1965年8月首次发布以来，WRC 107已被设计分析师广泛使用。尽管在接下来的几年里，分析方法和能力不断进步，实验数据不断增加，但这种持续使用强调了对WRC 107类型“烹饪书”的需求。这种需求的持续性是这项研究准备工作的一个主要推动因素？补充此处提供的WRC 297扩大了WRC 107的覆盖范围。本文给出了处理两个通常相交的圆柱壳的方法和数据，即径向连接到圆柱容器（壳）上的圆柱喷嘴。本公告给出了比WRC公告107更大的容器直径与容器厚度比的数据，为喷嘴直径与容器直径比的较小值提供了更好的可读性，并包括喷嘴颈部厚度的影响。第3节给出了计算接头附近容器或喷嘴应力的程序。 本公告以适用于设计工作的形式提供了SHELLTECH报告81-5中的表格数据。此外，还包括SHELLTECH报告80-2和SHELLTECH进度报告5（日期为1983年5月15日）中关于喷嘴柔性的数据。所用的分析方法由SHELLTECH的原理C.R.Steele根据薄壳理论推导和开发。

WRC 107 has been widely used by design analysts since its initial publication in August 1965. This continued use despite advances in analysis methods and capabilities and increased experimental data made available during the ensuing years underscores the need for a "cook book" of the WRC 107 type. The persistence of this need was a major motivating factor for preparation of this?Supplement?provided here in WRC 297 that broadens the coverage of WRC 107. In this document methods and data are given for treating two normally intersecting cylindrical shells, that is, cylindrical nozzles radially attached to cylindrical vessels (shells). This Bulletin gives data for larger vessel diameter to vessel thickness ratios than in WRC Bulletin 107, provides better readability for small values of the nozzle diameter to vessel diameter ratio, and includes the effects of nozzle neck thickness. Section 3 gives the procedure for calculating stresses in the vessel or nozzle in the vicinity of the junction. This Bulletin presents tabular data from SHELLTECH Report 81-5 in a form suitable for use in design work. Also, data on flexibilities of nozzles from SHELLTECH Report 80-2 and SHELLTECH progress report 5 dated May 15, 1983, are included The analytical method used was derived and developed by C. R. Steele, principle of SHELLTECH, on the basis of thin shell theory.
