讨论了形心的位置对惯性矩的影响以及根部约束对梁的变形影响。梁沿翼展的分布是采用经典的升力线理论得到的。过载为4，安全系数为1.5。该梁实由多种复合材料制成的上下非对称的变截面梁，在此基础上计算了梁的变形。计算结果与试验相吻合，说明该方法适用于梁的变形计算。

The paper discusses the effect of the location of centroid on the moment of inertia and that of root restriction on the deformation of the I-beam. The span-wise distribution is obtained by using the classical lift-ing-line theory with the load factor of 4 and the safety factor of 1. 5 . The deformation of unsymmetrical vari-able cross-section beams made of multi-composite materials is calculated. TBoth Both the calculation and. the experimentresults show that the method can be used to calculate I-beam deformation.
