【摘要】：為了研究軸向剛性系數(shù)對彎矩的影響,根據(jù)不同的軸向剛性系數(shù)對應(yīng)的彎矩不同,引入無量綱支座相對系數(shù)α,系統(tǒng)地研究不同荷載分布形式下對應(yīng)的α對彎矩的影響。通過分析得到:軸向剛性系數(shù)主要影響0~1.5邊跨范圍內(nèi)的彎矩,懸臂越大影響越小;彎矩與α1/3、α2/3存在線性關(guān)系;通過線性擬合,找到不同的荷載分布形式下α的變化對彎矩的影響,進而讓設(shè)計及研究者更加理解軸向剛性系數(shù)與彎矩之間的關(guān)系。
[Abstract]:In order to study the influence of axial rigidity coefficient on bending moment, according to the different moment corresponding to different axial rigidity coefficient, the influence of 偽 on bending moment under different load distribution form is studied systematically by introducing dimensionless relative coefficient of bearing. The results show that the axial stiffness coefficient mainly affects the bending moment in the range of 1.5 side span, the greater the influence of cantilever is, the smaller the influence is, the linear relationship exists between bending moment and 偽 1 / 3, 偽 2 / 3, and the influence of the change of 偽 under different load distribution forms on bending moment is found by linear fitting. So that design and researchers can understand the relationship between axial stiffness coefficient and bending moment.
