摘要
轻量化复合材料桁架桥是以碳/玻混杂纤维增强复合材料(FRP)与铝合金为原材料的,为武警部队研发、通行重型荷载的应急桥装备。为了验证桥梁的承载性能,对30 m跨轻量化复合材料桁架桥进行了静载与动载试验。结果表明:轻量化后的应急桥在静动载作用下,结构处于线弹性状态,杆件应力与桥梁变形均小于设计允许值,桥梁性能良好,达到了工程应用的设计要求。
The lightweight composite material(FRP) truss bridge is an emergency bridge equipment developed for the armed police force and used for heavy load.In order to verify the bearing capacity of the bridge,static and dynamic load tests were carried out on the 30 m span lightweight composite material truss bridge.The results show that the lightweight emergency bridge under static and dynamic loads is in a linear elastic state.The stress and deformation of the members are less than the allowable value of the design.The performance of the bridge is good and meets the design requirements of the engineering application.
