Abstract: | In this paper, based on the idea of finite element method, the initial parametric method in bending problem of a beam is extended to analyse the bar-system structure by employing Dirac function and Heaviside step function.Then a new method for analysing the internal forces and deformations of bar-system structure in space is suggested by improving the mixed method in statically indeterminate structure.The inferred process and obtained answer will be more succinct and accurate when the problem of internal forces and deformations of bar-system structure is analysed by using the new method provided in this paper. |
