Abstract


The portal frame building of light steel structure,have been widely used with less consumption of steel,and have obvious advantage on the period of the construction with comparison to the reinforced concrete structures.With the continuous development of society, the use of plant function has been changed. When the use of the new structure functions arising from the original conflict, in order to save resources, it is necessary to have the form of building construction for structural adjustment.In this paper the actual engineering, the application of portal frame design and optimization of the design of the basic principles of the basic principles that have been built portal frame structure of the optimal design, a detailed analysis of the calculation. Structure of different forms of steel to make the volume of statistics,and the performance of the structures to do the analysis, at the same time analyzing the merits and demerits of the two programs(Namely: the internal structure and the overall structure). In comparison, the system after the demonstration to determine the optimal programOn the basis of the best optimal program, apply the software of ansys finite element program ot analyze the form of structural arrangement and the area of Lasso parameter. To determine the final outcome of the optimization analysis,in order to meet the needs of practical engineering. In addition, the structure of this article also carried out the construction process simulation by the strength of the various stages of an analysis of characteristics, to guide the actual construction process.Our country’s rapid industrial growth, made the early stage of overheating investment,thus,the a large number of industrial plants be constructed. With economic development tends to slow, making some plants idle. In order to make full use of resources, the functional architecture will be built to change for the new construction in the future, such a situation will definitely become more frequent. This article not only to serve the project provided technical and theoretical support for such projects to provide a suitable template.
