摘要:
碳纤维布加固混凝土结构技术是近年来建筑加固领域的一项新型加固技术。分别对未加固和用碳纤维加固的钢筋混凝土梁建立了有限元模型,应用ANSYS软件进行了非线性有限元分析,研究了其挠度变化和极限承载能力等,并与试验结果进行了比较,有限元分析结果与试验数据吻合较好。研究表明,碳纤维加固钢筋混凝土梁可以显著提高其抗弯承载力。验证了本文的有限元分析方法的正确性,可以为实际工程碳纤维布加固混凝土梁的模拟提供参考。
Abstract:
Nowadays, the technology of using carbon fiber to strengthen the concrete structure is a new method in the field of concrete structure reinforcement. The paper presents the finite element models of non-strengthened RC beams and CFRP strengthened RC beams respectively, analyses the nonlinear finite element by using ANSYS code, and conducts the research of characteristics of deformation and the ultimate load-bearing capacities for the beams. The comparison of numerical values with experimental data shows that finite element results are in good agreement with measured values. The research indicates that the load carrying capacity of RC beams strengthened with CFRP can be increased significantly compared with non-strengthened RC beams. It also shows that the finite element ana1ysis method used in this paper is feasible and valuable in the further studies of RC beams strengthened with CFRP.
