| 摘 要： | 本文对非均匀弹性基础上变刚度梁弯曲和稳定计算进行了研究,导得通用的传播公式。编写程序简单,易于用计算机求解。 本文综合经典力法和位移法解静不定问题的思想,应用于传播矩阵法中,定义了“超静解传播系统”与“静解传播系统”等概念,给出並证明了一个求解“超静解传播系统”的定理。按此定理求解具有中间刚性支承和中间饺的多跨变刚度梁,原理简明,方便实用。最后经实例计算证明,结论是正确的,解法是有效的。

| Abstract: | Problem connected with non-homogeneity of mechanical properties of materials,besides being of great scientific importance,play a very significant role in many technical applications and engineering practice.By studying bending and buckling of non-homogeneous variable thickness beams based on non-homogeneous elasticity,the general solution,expressed by a standard fundamental set,is obtained,and also a concise and practical theorem of solving statically indeterminate transmissible system is given in this paper. |
