| 摘 要： | 对于变截面梁受弯变形位移的计算，文章利用样条函数构造位移函数，对样条节点之间的梁段进行刚度离散，先求出各梁段独立的势能泛函，再根据能量守恒原则及“势能求和”，利用变分原理使问题得以求解。本法满足一定的工程精度要求，易于编程，适用于桥梁、房屋等大跨度变截面梁结构的位移计算，具有一定的工程实际参考价值。

| Abstract: | As for the calculation of moving of SFPM of transect of deformed non-uniform beam, the article uses the displacement function of formation of the transect to dismiss the strength of the node. Firstly it calc, ulates the pan function of independent beam and then solves the problem with principle of conservation of energy and sum for dynamics. The method meets the demand of project requirement and can be used in replacement calculation of massive beam section projects like bridge and house. It has certain reference value for some projects. |
