摘要
将样条函数应用于框架等结构的极限分析,其优点是:结构刚度方程的形函数矩阵由样条函数组成,大大减少了原框架的未知量,且计算结果可满足工程要求。
Spline function to limit analysis of frame structure is applied.A new limit field foranalysis of frame structure is opened up.The advantage of structure rigldity equationconsists of spline function。Then the unknown numbers decreases 8reatly and that theresuIt of the computation satisfies the engineering request。
