摘要
介绍了基于力形函数和位移形函数的梁柱单元理论,将两种单元理论进行了对比分析,并编制有限元程序选取混凝土结构进行了非线性分析,通过实例的计算结果可见,基于力形函数的梁柱单元更具优势,且计算精度更高。
The paper introduces the beam-column element theory based on the force function and displacement function, compares the analysis of the two column theories, has a nonlinear function of the compilation of the finite dement procedure in choosing the concrete structure. It is proved by the examples that the beam-column based on the force function is advantageous and its accuracy of calculation is higher.
