For further optimization design, the influences of weldlength, stiffening rib and diaphragm plate for the web stresses distribution are studied and compared.
研究焊缝长度、加劲肋和横隔板等对腹板应力的影响，探讨锚固区设计的进一步优化。

But with the same length of straight seam pipe than the weldlength of 30 ~ 100%, and lower production rate.
但是与相同长度的直缝管相比，焊缝长度增加30 ~ 100%，而且生产速度较低。

Moreover, the difference of J-integral values increases with the increasing of the load and strength mismatching difference and the path-enclosed length of interface between weld metal and base metal.
