GFRP管道力学长期性能短时预测方法研究
THE SHORTER TIME PREDICTION METHOD OF LONG-TERM PROPERTY OF GFRP PIPES
摘要
Abstract
The certification of glass-fiber reinforced plastic (GFRP) piping systems is regulated by normative standards in which test series of 10,000 h are needed to predict the residual property of the expected life (normally,50 years).In this paper,the 1-4-4 combined optimal scheme for prediction of long-term property of GFRP pipe is proposed.This system involves using orthogonal design and test schemes lasting under 10,000 h.Experimental results for long-term ring-bending strain (Sb) of GFRP pipes from the standard test procedure indicate that this system is practical and effective.The estimation error when using the proposed method was consistently less than 5.24％ as compared to the standard method.关键词
