| 摘 要： | 有粘结体外预应力加固方法已经成为一种较成熟的加固方法运用在桥梁维修与加固工程中。应用有限元分析软件ANSYS针对不同配筋,不同截面形式的钢筋混凝土简支梁以及有粘结体外预应力加固简支梁进行模拟分析。同时结合试验分析结果,验证了现行的预应力钢筋混凝土受弯构件正截面极限承载力的理论计算方法对有粘结体外预应力加固方法的适用性。另外通过与桥梁加固工程中常用的其他加固方法进行比较,总结出本加固方法的优势。

| Abstract: | Bonded prestressed reinforcement system has become a mature method of reinforcement used in bridge repair and reinforce project.Reinforced concrete beams and bonded prestressed reinforcement beams with different reinforcement and different section forms have been analyzed with the finite element analysis software ANSYS.Compared to the test results,the theoretical calculation for ultimate capacity of prestressed concrete normal section can also be used in bonded prestressed reinforcement system.In addition,c... |
