sagging moment

基本解释

Clearly understanding the capacity of composite slim beam in the sagging moment region is the basis of structural analysis.
因此，明确正弯矩区组合扁梁的受力性能是进行结构分析的基础。
One is nonlinear buckling strength of stiffened panels and the other is longitudinal yielding strength of ship structures subjected to hogging and sagging bending moment.
二是船体在中拱及中垂弯曲下的总纵屈服极限强度。
The results show, in some cases, that the pressure against the soil foundation tends to be even, the sagging bend moment of the foundation beam is reduced and the hogging bend moment of the fo…
计算结果表明，在某些情况下，地基反力趋于均匀，基础梁正弯矩显著减少，而负弯矩则显著增大。

a bending moment that produces concave bending at the middle of a simple supported beam (Also called positive bending moment)
