【摘要】：为了研究轴向刚性系数对弯矩的影响,根据不同的轴向刚性系数对应的弯矩不同,引入无量纲支座相对系数α,系统地研究不同荷载分布形式下对应的α对弯矩的影响。通过分析得到:轴向刚性系数主要影响0~1.5边跨范围内的弯矩,悬臂越大影响越小;弯矩与α1/3、α2/3存在线性关系;通过线性拟合,找到不同的荷载分布形式下α的变化对弯矩的影响,进而让设计及研究者更加理解轴向刚性系数与弯矩之间的关系。
[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 伪 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 伪 1 / 3, 伪 2 / 3, and the influence of the change of 伪 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.
