Abstract

Electric Boat's submarine modular structures may contain trusses designed using elastic analysis methods for dynamic underwater shock loading. Suitable member sizes are partly determined on buckling criteria usually intended for design of columns subject to static loads and may be overly conservative for dynamically loaded columns, which can translate into added module weight and cost. In an attempt to understand the degree of conservatism, tensile and compressive tests were performed to determine material properties for structural steel in column and truss configurations both statically and dynamically. Through analysis of results, it's recommended that the members not be loaded beyond their static yield strength and that consideration be given to reducing column effective length factors.
