摘要
在分析现代无金属结构的民族化和高科技特征基础上,讨论了这种传统的新型结构在中国现代桥梁工程中应用会具有明显优点和前景,并可以较好地解决结构高强度、大跨度、耐腐、抗震、抗疲劳等重要要求,也有益于结构智能化控制等,但还需解决几个核心问题,如复合纤维与砼变形协调问题、预应力纤维砼结构的纤维筋张、锚方式等.
The evident advantages and application prospect of the modern nonmetallic structures and the traditional new structure style are discussed base on the characteristics analysis of the nationality and high-tech in bridge engineering,and the crucial requirements on the structures are met in aspects of high strength,longspan,corrosianrce,sistance seismic,stability fatigue,intelligent control and so on,but the rest problems are deformation consistency of FRP composite with concrete and FRP tendon prestressing, FRP tendon anchoring in the prestressed FRP concrete structures and so on.
