FRP作为一种新型高性能的结构材料,具有轻质、高强和抗腐蚀等特点,在土木工程中是一种具有发展前景的新型预应力筋用材.本文详细介绍了有限元软件ANSYS对预应力FRP筋混凝土梁的建模过程,并且将分析结果与体内有粘结和体内无粘结预应力FRP筋混凝土试验梁的试验结果进行了比较,验证了模型的可靠性.
As a new structural material, FRP (fiber reinforced plastics) features hght weight, high strength, cor-rosion resistance,etc., which has a bright future when used for a new type of prestressing tendon in engineering structures. This paper introduces how to use ANSYS in building the finite element modeling of pretressed concrete beam with FRP tendons. Then the finite element analysis of a bonded and a unbonded prestressed concrete beam with FRP tendons was made in ANSYS and the load-distortion curve was attained. Comparing with the test data, it indicated that the method was apphcable.
