·The forces acting on a ship may be static or dynamic.The static forces are due to the difference in the weight and buoyancy,which occur through out the ship.The dynamic forces are cause by the motion of the ship at sea and the action of the wind and wave.These forces create Longitudinal stress.Transverse stress. results for this questionWhat is conventional longitudinal strength?What is conventional longitudinal strength?The conventional longitudinal strength calcula- tion for a ship mainly concerns the elastic response of hull girder due to an assumed wave load and then,the elastic section modulus of hull girder,which is taken as the primary surveying index of the longitudinal bending strength,can be achieved by using the linear bending theory.A SIMPLIFIED APPROACH TO ESTIMATE THE ULTIMATE results for this questionWhat is the ultimate strength of a ship hull?What is the ultimate strength of a ship hull?A simplified approach dealing with the longitudinal ultimate strength of ship hull has been developed and an effective numerical program is implemented based on the individual components of ship structures.It is,then,possible to find the ultimate strength of the whole ship structure by evaluating those individual components.A SIMPLIFIED APPROACH TO ESTIMATE THE ULTIMATE

results for this questionWhat makes a ship stronger than a normal ship?What makes a ship stronger than a normal ship?To give longitudinal strength,the sheer strake and deck stringer plate are much heavier than normal,whilst the hatch side coamings are extra deep and are often made continuous throughout the ship.Sometimes,the hull is also extended upwards at the sheer strake,to form a strong box girder in place of the ordinary bulwark or rails.Strengthening the Ship Knowledge Of SeaCited by 6Publish Year 1988Author Hisayoshi Endo,Yoshiteru Tanaka,Genya Aoki,Hajime Inoue,Yoshiyuki YamamotoTechnical University of Denmark

longitudinal strength of the fore body of ships suffering from slamming A number of ships have sustained fatal forebody damage from heavy slamming in rough seas.The authors describe a series of model tests that were carried out to study the mechanism of such failures and to evaluate the ultimate longitudinal strength of hull forebodies by Longitudinal strength is also called as global strength.Global strength pertains to assessing the strength of the entire ship when it is floating in still water or in waves.Local strength,on the other hand,is about assessing the strength of a localised structure,like a girder or a longitudinal for loads experienced locally.Longitudinal Strength of Ships - an Introduction Was this helpful?People also askHow is the longitudinal strength of a ship calculated?How is the longitudinal strength of a ship calculated?For example,when calculating the longitudinal strength of a ship in a static sea,the vertical resultant force on the ship is zero,as the force caused by the buoyancy is exactly equal and opposite to the ship's self weight.Hence,for an F.E.analysis,a convenient set of restraints may be taken as shown in Figure 15.2.Longitudinal Strength - an overview ScienceDirect TopicsOcean and Naval Architectural DesignLongitudinal strength of transversely framed ships ~ contributions from deck,side shell,tank top and bottom plating; hatch/deck girders and bottom girders; not from local panel stiffeners.Loads Ship girder Loads,ship girder,steel Structural arrangements Longitudinal framing systems Midship section Deck,side shell,bulkhead
