Abstract: Statical analysis of infilled frame structure was conducted on 3D finite element models by means of software ANSYS10.0.
For a long time, Filling Wall is widely used in multi-storey buildings and Civil Construction Structures, for its flexible architecture flats and large interior space, etc.
However, because of the imperfection in analysis methods and the defects in model, pure- framework design is used in civil architectures, and the weight of filling wall is calculated by converting to the Line Load on the beam.

Abstract.
In the modern urban bridge projects,especially the urban interchange projects and the urban viaduct projects,the long-span curved bridge with the small radius is often inevitably used,considering the transportation under bridges,pipelines and aesthetic factors.This kind of long-span curved bridge with small radius was adopted on the south of Second Ring Road in Chendu of the project of “Two Expressways,Two Extended Roads,Two Ring Roads”.The influence,which the change of the parameters on the structure had,was analyzed by using the finite element software of Midas Civil 2010.Then,the parameter which had greatest impact on the inner force of the structure was found.The girder depth is the key parameter in design.
Fig.1 Horizontal plane of the bridge Fig.2 The section of the girder The Finite Element Model In general,the correctness of the establishment of the finite element model affect the error of the results directly.In the whole bridge structure calculation and analysis of modeling process,the following principles should be considered. 1) The requirement of structure shape change 2) The requirement of material characteristic change 3) The requirement of unit which link others characteristic change 4) The requirement of modeling the dead or live load 5) The requirement of the problem solving accuracy 6) The requirement of the convergence of solution (1)Based on the six requirements above,the finite element model was established by the finite element software of Midas Civil 2010.The boundaries were simulated accurately by adjusting direction of the local coordinates of nodes.Fig.3 shows the finite element model.
According to the most unfavorable load combination which was generated by Midas Civil 2010,it was adopted,which is “dead load+live load+support settlement+heating system+positive temperature gradient”.Table 1 shows the change of the parameters.
