scope:

This handbook contains algorithms for the calculation of characteristic dimensions of steel structural detail components using tee stiffeners in combatant, special auxiliary and assault ships of the U.S. Navy.

The structural details considered in this handbook address the detail components required for ordinary intersections of T-shape section-plate combinations, structural tube and I-beam stanchions. They apply for guidance in determining scantlings of flat plating and structures subjected to water pressure loads. They do not apply to special structures such as side protection bulkheads and submarine structures.

The structural shapes considered in this handbook represent those which are currently used in construction of U.S. Navy surface ships. The shapes considered in accordance with MIL-HDBK-264 have been limited to tee shapes (that is, channels and angles are excluded). The structural detail catalogs present unique structural detail pieces for application with standard rolled steel shapes. The algorithms presented can be used to generate special details for special application built-up sections.

The algorithms presented in this handbook have been derived from theoretical strength requirements and demonstrated empirical relationships based on cumulative shipbuilding experience with steel. Caution should be used in applying these algorithms to aluminum or stiffened panel structures of other materials.
