| Abstract: | A joint displacement calculation method of indeterminate bar with cosine function was discussed in comparison with ordinary energy method and graphic method. It was showed that the cosine function analytical method had advantages that the method was more concise and object and it produced more accurate calculation results. The method can be applied to some typical calculation of engineering structure. |
