The combined stress time history of ship hull's longitudinal component is obtained from combining the overall longitudinalbending stress with local bending stress.
These supports, in addition to carrying local loads from cargo, etc, serve to keep the deck and bottom from moving toward each other as a result of longitudinalbending of the hull girder.
这些支撑，除运载来自货物等等的局部载重之外，也保持甲板和底部避免由纵向船体纵桁弯曲造成的相互位移。

Cyclic bending tests of a box girder with longitudinal stiffeners were also carried out.
