偏心导致的结构承载能力下降的设计修正

Design Update of the Carrying Capacity Decreasing Resulting from Eccentricity

起重运输机械钢结构设计过程中,有时为了避免干涉,会设计出偏心的结构。这种结构会造成附加弯矩的产生,从而导致结构从拉压构件变成压弯或拉弯构件的情况。分析了这种结构的危害,并结合实例介绍了其修正方法。

To avoiding the structure interfere, eccentric construction is designed in the process of crane＇s structural design. The additional bending moment in the structure will change the structure from compressed structure to press bending structure. This paper analyzed the danger of eccentric construction and give an example for specification.
