تعیین سطح عملکرد تیرهای بتن مسلح مقاوم سازی شده با الیاف پلیمری مسلح شده (FRP) با استفاده از مدلسازی عددی المان محدود

In recent decade composite material has been used in order to increase the effectiveness of reinforce structures. The difficulty of numerical modeling of beam by finite element method, is a problem encountered during such study. Destruction of structures such as building, bridges, etc, due to earthquake and time-dependence erosion, Highlight the need for reinforcing the structures. Today, Many researches have been done to estimate the efficiency limit and strength of structure made of reinforced concrete. Because of time and expenditure needed for experimental methods, numerical methods have been used as an acceptable method for this problem. In other hand, in numerical modeling, one has to define the none linear behavior of reinforced concrete material and fiber (FRP) reinforced polymer. In this paper, numerical models with ABAQUS software, incorporating proper constitutive models calibrated with experimental results.
