摘要
为研究复合材料在桥梁工程中的应用,以天津某复合材料人行桥为研究对象,采用ANSYS 11.0建立该桥空间有限元模型,对其进行结构验算与分析。分析结果表明,通过合理的结构设计和材料设计,复合材料桥梁可以满足现行的规范要求。最后探讨了复合材料桥梁设计面临的技术困难——结构设计准则和结点连接技术,并根据当前国内外复合材料的发展和环境恶化的加剧,对复合材料桥梁的应用前景做了展望。
To study the application of composite materials in bridge construction,a GFRP pedestrian bridge in Tianjin was taken as the research object,by using ANSYS 11. 0 to build the bridge finite element model for checking and analyzing its structure. The results showed that composites bridge can meet current regulatory requirements,through reasonable structural and material design. At last,some principles of design and joints connecting were discussed,because they are the most complex problem in the design process. According to the current development of composite materials and the deterioration of domestic environment,the application prospect of composite bridges will put forward.
