【摘要】 采用自行研制的FRP筋材高温力学性能测试系统,对玻璃纤维增强塑料筋GFRP在高温下的受力变形性能进行测试。结果表明,采用本文的试验方法可得到GFRP筋在火灾下真实的受力变形曲线,而高温下GFRP筋的破坏特性与常温下有显著不同。更多还原

【Abstract】 By means of self-developed High Temperature Testing System for fiber reinforced polymer bars,the mechanical performances of stress and strain for glass fiber reinforced polymer bars were tested at elevated temperature.It indicates from the test results that the real stress strain curves of GFRP at elevated temperature can be obtained using the test method in this pa- per,however,the failure characteristics of GFRP at high temperature differs remarkably from that at normal temperature.更多还原
