MAESTRO: 

MAESTRO Additional Capabilities: Underwater Shock and Whipping Interface with “USA” shock code Collapse Load of Cylinders Using API’s Bulletin 2U Ultimate Longitudinal Bending Strength Using Adamchak’s ULTSTR method Overall Structure Vibration

Specification of Loads in MAESTRO: 

Specification of Loads in MAESTRO Lightship mass distribution Selfweight, actual or scaled Distributed masses (e.g., weight curve) Large selected masses (e.g., engines) Hydrostatic loads: stillwater and waves Internal tank fluid mass loads Cargo masses (containers & bulk cargo) Accelerations (6 d.o.f.) Pressure loads, actual and design Point loads (forces and/or moments) External bending moment and shear force at ends of partial models

Overall Failure Modes: 

Overall Failure Modes OVERALL STRUCTURE Progressive collapse Fatigue Bending deflection limit Bending stress limit Static Low frequency waves, live loads Medium frequency vibration whipping slamming Transient (via USA) U/W shock

Individual Member Failure Modes: 

Individual Member Failure Modes PANELS Collapse stiffener flexure combined buckling membrane yield stiffener buckling Stiffener yield compression, plate & flange tension, plate & flange Plate unserviceability yield transverse bending longitudinal bending local buckling allowable permanent set pressure loads concentrated loads GIRDER Collapse torsional buckling plastic buckling, flange plastic buckling, plate Yield compression, plate & flange tension, plate & flange FRAME Collapse, plastic hinge Yield compression, plate & flange tension, plate & flange
