Structural Design And Scheme Study Of Yaping High-Rise Sightseeing Elevator On Maoyan River,Zhangjiajie

In this paper,the actual project of Yaping high-rise sightseeing elevator on Maoyan River,Zhangjiajie is taken as the research object,and several structural schemes are analyzed and compared by means of finite element analysis.Finally,the optimal structural design scheme is obtained,which provides reference for the structural design of similar sightseeing elevator in the future.The main contents of this paper are as follows:(1)This paper introduces the types of high-rise sightseeing elevators in detail,and through collecting the relevant data and literature of the domestic completed projects,understands the structural forms of various high-rise sightseeing elevators,the characteristics and applica ble scope of the supporting modes,and discusses the key contents of the design of high-rise sightseeing elevators;(2)This paper summarizes the main methods of structural design,including the four steps of preliminary scheme design,structural analysis,structural design and submission of results.Taking Maoyan River high-rise sightseeing elevator in Zhangjiajie as the engineering background and buttress tower structure as the research object,different structural schemes are determined,including rectangular tower,hexagon tower and eight support models.And the material,section form and size,restraint mode and load combination of components are preliminarily determined to prepare for the subsequent research.(3)Through Auto CAD 3D modeling,Midas Gen completes the establishment of structural model,carries out static elastic analysis and steel structure checking calculation for each structural scheme,obtains the structural model meeting the specification requirements after repe ated adjustment,and obtains the better structural scheme through the comparative analysis of the calculation results,including the stress situation,displacement situation and material consumption;through the analysis and comparison of the stability of each structural scheme,Finally determine the best structure.(4)Finally,Midas Gen is used to study the seismic performance of the optimal structural scheme.The analysis contents include: Response spectrum analysis of mode decomposition,elastic time history analysis under frequent earthquakes and elastic-plastic time history analysis under rare earthquakes,so as to understand the mechanical performance and safety of the structure under earthquake.
