高性能材料FRP应用与结构工程创新

Application of high performance FRP and innovations of structure engineering

在21世纪,混凝土结构将继续大力发展和应用。它对新材料提出了挑战。简述了很有发展前景的CFRP及AFRP、GFRP的优良性能以及它们在国内外土木工程中的应用。简要介绍了结合国家自然科学基金项目研究、设计并在江苏大学内建成了中国第一座高性能CFRP拉索独塔斜拉桥,桥长51.5m。最后,提出了合理应用FRP及结构工程师应该做些什么的问题。

In the 21th century,concrete structures will still obtain great development and wide application continually. It puts forward challenges to new materials.The excellent performances of CFRP、AFRP and GFRP,which have wonderful development prospect,and the applications of them in civil engineering at home and abroad are introduced briefly.Based on the National Natural Science Fund Project,we designed and constructed the first cable-stayed bridge with high performance CFRP cables in China,which has one tower and is 51.5 metres long.Finally,the proper applications of FRP and what the structure engineers should do are brought forward.
