摘要:
采用花旗松胶合木作为芯材,玻璃纤维增强复合材料(GFRP)作为面层制备夹芯结构桥面板,在对花旗松胶合木芯材和GFRP开展基本力学性能试验研究的基础上,开展了GFRP-花旗松胶合木夹芯梁的受弯性能试验,得出了其荷载-跨中挠度曲线与GFRP荷载-跨中应变曲线,并对抗弯刚度测试值与理论计算值进行了对比;针对某GFRP-花旗松胶合木桥面板,提出了完整的结构设计流程,给出了桥面板的合理设计参数。研究结果表明:GFRP-花旗松胶合木桥面板应用于钢梁-复合材料桥面板组合桥梁结构较为可行。
Abstract:
The bridge panel of sandwich structure was manufactured by using pseudotsuga taxifolia glulam as core materials and glass fiber reinforced polymer (GFRP) as surface course. The bending experiment of GFRP-pseudotsuga taxifolia glulam beam was carried out based on basic mechanical property of pseudotsuga taxifolia glulam core materials and GFRP. From the bending experiment, the loadmidspan deflection curve and GFRP loadmidspan strain curve were got, and the test value was compared with theoretical value of bending stiffness. It brought up a whole structured design process of a sandwich structure bridge deck, and gave the design parameter of bridge deck. The study results show that using GFRPpseudotsuga taxifolia glulam bridge deck into girdercomposite bridge panel is feasible.
