Longitudinal Strength of Ships - Hogging and Sagging

The sagging and hogging bending moments and shear forces are hull girder loads.The hull girder loads are balanced by internal forces and moments affecting at a crosssection of the ship hull (stress resultants) The accurate prediction of the extreme wave loads is important in the ultimate strength assessment of the hull girder.Lecture 15C.1 Design of Tanks for the - UL FGGIn that event a kerb angle is also required at the free edge; the arrangement of a low ring girder and a kerb angle is covered by the design rules.4.4 Secondary Wind Girders Although the primary wind girder or the roof will stabilise the tank over its full height,local buckling can occur in empty tall tanks between the top of the tank and its Lecture 15C.1 Design of Tanks for the - UL FGGIn that event a kerb angle is also required at the free edge; the arrangement of a low ring girder and a kerb angle is covered by the design rules.4.4 Secondary Wind Girders Although the primary wind girder or the roof will stabilise the tank over its full height,local buckling can occur in empty tall tanks between the top of the tank and its

Yes,see Section 5.9.4.2 and Q.3.4.7. if Wc is greater than the vertical leg length of the angle or thickened bar,can the remaining portion of Wc be included as participating in the included area of the compression ring? Yes.Page 3 of 11.How to Design Cylindrical Tanks? Civil EngineeringThe joints in the bottom of the tank are covered by T bars inside and turned upto form vertical stiffeners at the sides.All outer joints will be covered up by cover plates.The tank will be supported on four longitudinal girders at 2 metres centres which in turn will rest on beams carried by 6 metres high columns.Design of Bottom Plates:Hopper Design Principles - Chemical Engineering Page 1The angle of wall friction () is obtained by following the method described in ASTM D-6128 [2].The test is performed using an instrument (shown in Figure 2) that involves placing a sample of powder inside a retaining ring on a flat coupon of wall material.
