Abstract: Current trunnion joint design practice is very conservative. The detailed engineering designs for trunnion are empirical and dependent on the ingenuity of experienced engineers using empirical equations for design checks. The objective of this study is to close this gap and provide a more rational design approach through a comprehensive experimental and numerical research program. The results have proven that brace contributes significantly to the static strength of the trunnion. An analytical approach to the trunnion design provides a complete table where pure pipe trunnion could be selected where failure mode is governed by shear and not chord indentation. A new approach was also introduced in using through pipe trunnion that extends the boundary by reducing the effects of chord indentation so that full static strength of the trunnion joint can be mobilized.
