| 摘 要： | 研究了变电构架承载能力对杆件各种参数的灵敏性,并提出计算结构对于构件参数变化的灵敏性分析程序,进而以3个变电构架为例讨论结构对不同构件的灵敏性,比较不同位置构件的重要性.结果表明,结构对柱子比对梁更加灵敏,也即柱的重要度高于梁,受压柱高于受拉柱,中柱高于边柱.

| Abstract: | It takes three power transformation structures as example and studies the sensitivity toward member parameters. And it puts forward a calculation procedure for structure’s sensitivity to the different members. Computing results indicate that the power transformation structure is more sensitive toward columns than beams. |
