| 摘 要： | 以坐落在俄罗斯远东地区符拉迪沃斯托克市的轻质钢桥为研究主体，利用现场实测及理论分析对轻质钢桥进行动力学参数评估。结果表明:实际测得振动周期与理论计算值基本吻合，而轻质钢桥的自振周期不符合俄罗斯桥梁设计规范。为改善轻质钢桥的动力特性，提出了采用加铺混凝土方案和准确评估轻质钢桥的动力学特性需要全面考虑结构的组成细节，并建立有限元模型的必要性，其结果具有一定的理论意义和工程实践应用价值。

| Abstract: | Based on steel bridge constructed in Vladivostok of Russia, the dynamic characteristics of light weight steel bridges are studied in this paper. The dynamic characteristics are studied by theoretical analysis and field test, and the calculation results are consistent with its real performance. But the vibration period of light weight steel bridge does not accord with the requirement of the bridge design. To improve the dynamic characteristics of the light weight steel bridge, casting concrete topping is suggested, and it is very important to take into account details of structure and to construct finite element model for accurate estimate of dynamic characteristics. The result of this paper has certain theoretical meaning and application value in engineering practice. |
