【摘要】 本文给出了非均匀变截面连续梁稳定性状态方程的一般表达式。并依此得出了500千伏变电构架A字柱平面外稳定性的状态方程,与文献[3]的结果完全一致。证明了本文采用方法的正确性,也说明了本文的方法优于文献[3]的方法。更多还原

【Abstract】 In this paper, a general state equation of stability for continuous beams with uneven cross-section js presented first. Then a state equation of stability out of frame plane of A-pole used in 500kV substation is derived, and the result is identical with that in reference ( 3 ) . It means that the method presented have is correct and is better than that in ( 3 ) .更多还原
