失稳系数 meaning in English

buckling factor

In the end , the steel - reinforced concrete arched bridge ( chun ' an weiping bridge ) , which span is 198m , is analyzed by the proposed three - dimensional nonlinear finite element method and also those gained conclusions are directly adopted in the computation . the universal stability coefficient and nonlinear buckling stability coefficient of the bridge are respectively computed , in which the dead load and the live load are assembled according to the criterion . on the other side , the regularities of creep deformation and subsidiary stress of the investigated bridge under the first - stage dead load are carefully researched
最后，将本文所提出的三维非线性分析方法及其主要研究成果直接应用于198m跨劲型骨架式钢管混凝土拱桥“淳安威坪大桥”的分析计算中，对该桥在最不利恒载和活载组合下的一般特征值失稳系数和非线性屈曲系数进行了对比研究，并对一期恒载长期作用下该桥的徐变变形、附加应力以及截面应力、应变重分布规律分别进行了深入研究。
