变惯性矩梁变形的近似计算

Approximate calucation of the variable moment of inertia beams deformation

对于惯性矩连续变化梁的变形计算,给出了一种简便近似的计算方法,以使变惯性矩梁变形计算转化为等惯性矩梁变形计算,从而可以避免积分,直接查表计算,适用范围较广。

On continuonsly variable moment of inertia beam deformation calculation. A simple approximate method is given to convert variable moment of inertia beam deformation calculation into constant moment of inertia brem deformation. The calculation result, which can meet accuracy requirement and be suitable for project application,can be obtained directly from the table.
