moment strength
3.And will develop the procedure will use in producing actually the rolling strength and the moment of force computation, by the time realization rolling strength precise forecast, the craft parameter determination and the rolling mill will design for the actual production in when the rolling strength can the parameter choice provide the method.
7.Three-dimension drilling stem strength analysis based on considering the torsion load and studies deformation, bend-moment, stress, the distribution characteristics of RWD BHA was made .
8.Using method of finite element, this paper shows that the continuous composite beams have these properties of moment excess in middle span and stress lag of negative steel in abutment. These properties result in plastic redistribution of section internal force between middle span and abutment, which enhance flexure strength, crack resistance and ductility.
9.From the Study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment, by which the first approximate value of hull midship section modulus can be determined.
10.Because the intervals of two side girders are relatively large in the structure of the floor, it is not even and some and out of shape that its bridge of panels must be produced at the same time horizontally and crookedly and vertically except deforming wholly, level analyse can receive the satisfied result already at this moment, is it is it accord with floor structure real work state , girder of cable-stay bridge just to analyse with whole out of shape relevant non-linear space of function while being out of shape while being above-mentioned to consider only, but about this research rarely seen to report bridge worker is it understand their receive strength characteristic in an all-round way to need badly publicly.
