| Abstract: | The common methods to simulate the prestressing force tension of beam string structures(BSS) by finite element method(FEM) are introduced in this paper.The force method,equivalent decreasing temperature method and initial strain method are compared,and the characteristic of each method is also introduced.A numerical example is analyzed and the results demonstrate that the equivalent decreasing temperature method is most appropriate.Some problems for BSS are also listed for the further researches. |
