【Abstract】 In this paper, based on the idea of finite clement method, the initial parametric method in bending problem of a beam is extended to analysis of the bar-system structure by employing Dirac δ function and Hcavisidc stcp function. Then a new method for analysis of the initial forces and deformations of bar-system structure in space is suggested by improving the mixed method in statically indeterminate structure. All inferred process and obtained answer will be more succinct and more accurate when the problem of intcrnal forces and deformations of bar-system structure is analyscd by using the new method providing in this paper.更多还原
