We should check mainly the strength, stiffness and stability of MSS in these conditions In the end of this paper, we also do some research about design optimization of MSS62.5 girder, establish a parameter model which set some parameters as design variables such as girder high、Web thickness、web opening shape and size; other parameters as restrictive conditions such as a main girder stress and stiffness and the volume of main girder steel as the objective function by ANSYS optimization module. The analysis results show that the main girder should been composed of sub-section of variable thickness steel plate which is opened with variable highness round-ended holes in the web. This can increase the stiffness of the main girder while reducing the weight. and it has many advantages such as reasonable-uniformly structure stress、saving material、lower cost of design, processing and transportation and soon.
