Abstract:
The basic purpose of applying the Prestressing technique in steel structures, weight decrease of sections because of is increase their load-carrying capacity that this eventually led to the realization of technical and economic advantages of such structures are. In this paper, prestressing method in steel I-beams, as post-tensioning of the external tendons installed in various samples of steel beams, to determine the increase of flexural strength and improve of load capacity, is analysis and evaluation by the finite element software of ABAQUS. Considering the existence of experimental results in this study, and comparison between these results and analysis done for each of the samples, among them a suitable corresponded can be observed and applying the prestressing technique, Flexural behavior of beams in the form of indicators such as stress, strain and displacement bottom flang of the beem in the mid-span, are all significantly to be improved.
