A tri-beam model can be built from simplifying SWATH,and its numerical simulation of response of wave can also be achieved.

The triple-girder model can consider the warping constant of deck and can calculate the warping frequency of the structure of cable-stayed bridges,which can be applied to an mechanical model of deck with an open cross section.

This paper attempts to put forward the scheme design idea of bridge model by the analyzing design requirements of the model and load methods in the match of the structure design,and choose structure design schemes.

Taking the middle pier of a grade separation bridge in Beijing City as the example, the article carries out the vibrostand experiment study of the bridge model earthquake reaction, and investigates the influence of the model earthquake reaction on the rubber support in layers, which provide the experimental basis for the anti-earthquake design of the bridge structure.

The general testing scheme of large-scale bridge model including static test, dynamic test and pseudo dynamic test are presented briefly in this paper.

Research methods:Using finite element theory,beam-slab models of plane slab and frame slab ballastless tracks are built,the model calculation is caught by the finite element tool software ANSYS.

Building damage due to diferential settlement was evaluated using the deep-beam method together with a damage criterion.
