FRP筋和钢筋混合配筋混凝土梁受弯性能数值模拟及理论分析
NUMERICAL AND THEORETICAL ANALYSIS OF FLEXURAL BEHAVIOR OF HYBRID FRP-STEEL REINFORCED CONCRETE BEAMS
摘要
Abstract
Recently,the reinforced concrete structure with a hybrid combination of FRP and steel bars has already become a hot topic of research in civil engineering community.In this paper,a 3D finite element model of the hybrid FRP/steel reinforced concrete beams was set up using the software ANSYS based on the test data.The whole bending process of the hybrid FRP/steel reinforced concrete beams was analyzed.Then the concept of a nominal reinforcement area of the hybrid FRP/steel reinforced concrete beams was proposed and used to set up a theoretical model combining with the technical code for infrastructure application of FRP composites.The load capacity and deflection of the hybrid FRP/steel reinforced concrete beams were estimated by using the theoretical model.The comparisons between numerical/analytical results and experimental date demonstrate the reliability of both the proposed FE model and the theoretical model.关键词
