| Abstract: |
Scale model experiments have been widely used in short- and medium-span bridge research, including B- WIM technology and vehicle-bridge interaction mechanisms and applications. A high simulative scale model can be used to verify the relevant theories and technologies effectively. In this paper, a 1:20 scale model has been set up according to a 3×20m three-span continuous box girder bridge prototype. The physical quantities of the scale model have been derived by similitude law to guide the model design. Appropriate materials, such as PMMA and lead blocks, have been adopted to form the basic structure, whose arrangements are detailed. Finite element analysis (FEA) is applied to calculate and compare the static and dynamic characteristics between real bridge and model structure. One experiment case of a B-WIM test integrating influence surface and computer vision has been carried out to illustrate the model's validity. The constructed model can be a useful platform for future researches and provide a reference for practitioners. |
