摘要
针对摩天轮下部支承结构的受力性能进行计算分析。本项目为加固改造项目,原有商业屋顶新增设摩天轮,为保证新增摩天轮与原结构主体受力不相互影响,增设内、外支承结构承托摩天轮。针对摩天轮支承结构进行分析,采用两种计算模式:摩天轮作为外加荷载作用于支承结构,单独分析支承结构受力性能;摩天轮和支承结构作为一个整体,通过整体分析模拟支承结构与摩天轮整体在各种工况作用下的受力性能。通过两种不同计算模式,分析支承结构的承载力和位移,以保证结构的安全性。
The mechanical performance of the lower supporting structure of the Ferris wheel is calculated and analyzed.This project is a strengthening and reconstruction project.A new Ferris wheel is added to the original commercial roof.In order to ensure that the stress of the new Ferris wheel and the main body of the original structure does not affect each other,internal and external supporting structures are added to support the ferris wheel.In this paper,the supporting structure of Ferris wheel is analyzed,and two calculation modes are adopted:Ferris wheel acts on the supporting structure as an external load,and the mechanical performance of the supporting structure is analyzed separately;the mechanical properties of the ferris wheel and its supporting structure under various working conditions were simulated through the whole analysis.Through two different calculation modes,the bearing capacity and displacement of the supporting structure are analyzed to ensure the safety of the structure.
