浮桥通常由多个桥节拼组而成,增大单个桥节构型尺寸可以提高其海上拼组架设效率和车辆通行时的安全性.但随着桥节构型的增大,其自身弹性变形更加显著.为了求解一个300 m长的铰接浮桥在波浪中的结构响应特性,提出了一种基于等效弹性铰接的多浮体模型模拟单个桥节的海上浮桥动力响应计算方法.首先,基于弹性基础梁模型和铰接多浮体模型的位移等效处理,求解出由弹性铰连接的多浮体模型中弹性铰的转动刚度;然后,利用ANSYS-AQWA软件进行多浮体模型的水动力分析;最终,得到了该浮桥在不同波浪环境中的垂向位移、弯矩、剪力分布特性和系泊系统受力情况.

In this paper, a theoretical calculation method that can be generally applied to responses analysis of irregular bridge span pontoon connected by elastic hinges was proposed based on the elastic foundation beam theory. This method can solve the displacements, rotation angles, bending moments and shear forces of pontoon bridge under vertical static loads. By comparing with the experimental and numerical results in other researches, the correctness and universality of theoretical method are verified. The main response characteristics of the pontoon bridge under vertical static loads are further investigated based on a detailed case study, which contrasts the results of three methods including the theoretical method in this paper, AQWA software and FEM. The results reveal that the rotation stiffness of elastic hinges has a great influence on the responses of the pontoon bridge. The elastic deformation of the pontoon units can be ignored when the rotation stiffness of hinges is small, while it needs to be considered seriously when the rotation stiffness of hinges reaches a certain value. Besides, the flexural rigidity of pontoon bridge also has a sensitive influence on the numerical results. The theoretical method can provide for the optimal design of the pontoon bridge and has significant engineering application prospects.

A reliable and applicable finite element (FE) model is the basis of the research works, but the traditional spine FE model of long span bridges can not satisfy the needs of structural health monitoring and condition assessment. Therefore, it is necessary to conduct multi-scale FE modeling orient to different research objectives and requirements. The Runyang Suspension Bridge (RSB) is taken as an example. In order to increase the accuracy of analysis results, a 3-dimensional whole FE model for the RSB is established with FE program ANSYS and the spatial submodel of the steel box girder is then particularly established. After the feasibility and superiority of the submodel method is demonstrated, the connection of the multi-scale models is realized based on the submodel method. On the basis of the analysis results from the whole model and the connection of these two models, the local stress of the steel box girder under various vehicle loads is calculated with the submodel method. The calculation values are proved to be accurate by the measurements of the field test, which shows that the efficiency and reliability of the multi-scale FE models and the connection technique with the submodel method. The results obtained in this paper can not only provide research basis for health monitoring and condition assessment of the RSB, but also have theoretic references for analyzing and designing the steel box girder of other long span bridges.
