Optimization Design Of The Large-span Transport Corridor For Construction Lifter Based On ANSYS Workbench

In recent years, with the increase of the world population, land resources are very lack now, the housing shortage problem is becoming more and more serious, the traditional sense of the housing has been unable to meet the people’s needs. In this case, high-rise buildings emerge as the times require. The high-rise building at home and abroad is developing to the direction of energy saving. With the rapid development of high-rise buildings in the global scope, the shape is to art direction. For non conventional irregular buildings, construction elevator transport channel building requirements are also improved, especially the span problem is particularly important. Now, with the construction of large span lift transport channel is generally relying on the building material to build, and no substantive progress on its safety. In order to save material and improve the safety of the structure, the research of large span corridor will have great development space.According to the different layers and the shape of the high-rise building, to build a transport channel is not the same length, for example,1-8 meters, and there are longer. In this paper, only for the 8 meter span transport channel to analyze and optimize:First,according to the requirements of the company, put forward two kinds of construction hoist, and mechanical knowledge were carried out theoretical analysis for these two kinds of structure, a theoretical basis is obtained, and then use the software ANSYS Workbench to carry on the processing and analysis. Finally, according to the comparison results of the software and the theoretical results: the two kinds of 8 meters span transport channel structure, which the first is not in conformity with the requirements, only the second kind of structure in order to meet the basic requirements.Second,based on the above two kinds of structure, in order to decrease the economic cost, put forward three kinds of structure programs which to optimize construction hoist 8 meters span transport channel. The process is followed by reduction of the number of steel and using the ANSYS Workbench finite element analysis is carried out the three kinds of structure, and obtained the stress and deformation chart. Finally, according to the results, these three kinds of optimization of the structural strength and stiffness are within limits, but from an economic point of view, we adopted the third kinds of structure, which has the minimum safety and cost advantage.Third,the safety analysis for the 8 meter span transport channel optimized which is the third kind of structures, In this paper the two kinds of structure lack of a pole is given, then use ANSYS Workbench to analyze the structure of the construction hoist 8 meters with finite element analysis, and then sum up. Finally, according to the stress and deformation amount and find out the key link.
