摘要

为了研究纤维缠绕FRP管在地震作用下的极限弯曲状态，我们对FRP管在1.4MPa的内水压下进行了四点弯曲试验。采用四种不同比例的十二根管子进行试验。试验结果表明，管道的破坏形式和强度与管道的比例有关。根据管材的尺寸设置允许弯曲能力是合理的。

Study on Ultimate State of Filament Winding FRP Pipes Under Bending Force

To investigate of ultimate state of filament winding FRP pipe against bending force caused by earthquake, we perform four-point bending test of the FRP pipes with 1.4MPa inner water pressure. Twelve pipes with four different proportions are applied to the test. The test results show that the damaged form and strength depends on the proportion of the pipe. It is considered reasonable to set the allowable bending capacities according to size of the pipes.
