| 摘 要： | 介绍钢结构弹塑性分析的样条有限点法.首先用混合参数法构造了样条基函数,在此基础上将梁单元进行单样条离散,建立了梁单元的样条离散化总势能泛函,利用最小势能原理,最终得到薄梁的挠度及弯矩.根据上述方法并结合FORTRAN语言的矩阵运算优势,编制了样条有限点法的FORTRAN程序.通过典型算例分析,结果表明此方法计算简便,精度高,经济有效.

| Abstract: | The spline finite point method for elasto-plastic analysis of steel structure is introduced.First,the spline primary function is given by hybrid parameter method;then the beam element is dispersed by the single-spline function,the spline dispersing total potential energy functional;the deflection and moment of the beam element are reached by Principle of Minimum Potential Energy.Basing on the above theory and the advanced matrices operation of FORTRAN program,a FORTRAN program of the spline finite point met... |
