| 摘 要： | 对复杂载荷下变刚度静不定梁建立了一种通用力学模型，得出梁任一截面的变矩方程。通过对变矩方程的积分和积分后方程的递推，推导出梁任意截面的转角和挠度变形的一般方程，并给出工程计算实例。该方程易于采用计算机处理，为复杂载荷下变刚度静不定梁程序化求解提供基础。

| Abstract: | In this paper,a kind of general mechanics model of variable-stiffness statically indeterminate beam under complex load has been established,and the equations of bending moment at arbitrary section of the beam are obtained.The general equations of rotation angle and flexibility deformation at arbitrary section of beam were derived by means of the integral to bending moment equations and the iteration of the equations after integration.And the living computational example of engineering was given.These equations are easily processed by computers,thus provided a foundation for programmed solution of the variable-stiffness statically indeterminate beam under complex load. |
