Duration Phase ~ 2,000 labor hours over ~ year Phase 2 2,000 labor hours over ~ year Phase 3 2,000 labor hours over ~ year SY/9~D-S Consistent Stochastic Analysis Procedure for Design of Floating Marine Structures Objective Develop and implement a consistent stochastic analysis methodology integrating structural and hydrodynamic analysis of floating manne structures subject to waves. The structural analysis of the methodology should be finite-element based and suitable for production use In design.

· Solve a complex, realistic ship-structure/manna-structure problem and compare deterministic and stochastic finite-element method results. Duration Phase ~ 2,000 labor hours over ~ year Phase 2 2,000 labor hours over ~ year Phase 3 2,000 labor hours over ~ year SKC/9SD-T Nonlinear Rolling of a Lightship Tanker and Other Shallow Draft Structures Objective Evaluate the rolling motion of a shaBow-draft vessel, which cannot be determined by a conventional analytical tool.

Benefit Results of this project would provide the basis for reliability assessment and probabiliW-based design for novel marine structures. Background A 5-year research program to apply reliability technology to marine strictures and to develop probability-based design criteria for ship structures has been initiated by the SSC.

· Study the literature on structural reliability, particularly as it relates to special marine structures, including SSC-sponsored reliability projects. · Study documentation of the American Institute of Steel Construction-Load and Resistance Factor Design, American Petroleum Institute-Ioad and resistance factor design, the Canadian Standard Association's proposed program for offshore structures, and other relevant literature on probabilistic design-code development, particularly that literature related to marine environments.

SSC National Goal Improve the safetr and integrity of marine structures. SSC Strategy Prevention research including damage-tolerant structures, structural monitonng, and human factors Background Much progress has been made recently In the area of design for the minunization of corrosion, and this knowledge is currently being implemented.

~ the specimen contains very small defects, Belying would spread outside the uncracked tip root ligament area, resulting in a gross section or general yielding condition. When this happens, the crack-tip stress field does not relate to the applied fracture parameters as it does for net section yielding, and a fracture toughness measured for standard-sized cracks may be overly conservative when used to predict fracture of structures with small defects.
