小变形轴力杆件的变形位移方程

Deformation-displacement equation of axially loaded bars with small deformation

  • 摘要: 从杆件变形量的定义出发,利用两点间距离公式,导出了小变形轴力杆件的变形位移方程. 此方程形式简洁,计算方便,对线性和非线性材料的小变形问题都可应用,也不必区分静定结构和超静定结构,还可以方便地处理支座沉陷问题,因而广泛适用于桁架结构的受力分析.

     

    Abstract: Using the formula of the distance between two points , the deformation-displacement equation of axial force bars with small transfiguration is educed from the definition of bar's deformation. This equation has a pithy form, is easy to calculate, can be applied to solve the problems of small deformation of either linear or nonlinear materials, has no need to distinguish between statically determinate and indeterminate structure, can handle pedestal subsidence easily, thus is suitable for use to analysis truss structures widely.
