The fatigue damage evolution in glass-fiber-reinforced (GRP) mortar pipes under cyclic loading were investigated. Based on the results of fatigue tests, a two-stage linear law of stiffness degradation of a glass-fiber-reinforced plastic mortar pipe culvert is proposed, and a model for calculating its stiffness degradation is established. By proposing a reasonable residual stiffness calculating equation, this study intends to provide a useful method for an accurate prediction of the fatigue life and a valid long-term safety evaluation of GRP mortar pipes.

GRP砂浆管涵疲劳损伤性能试验研究
研究了玻璃纤维增强 (GRP) 砂浆管在循环载荷下的疲劳损伤演变。根据疲劳试验结果,提出了玻璃纤维增强塑料砂浆管涵刚度退化的两阶段线性规律,并建立了其刚度退化计算模型。通过提出合理的残余刚度计算方程,本研究旨在为准确预测玻璃钢砂浆管的疲劳寿命和有效的长期安全评估提供一种有用的方法。
