基于ETABS的超高层建筑施工塔式起重机验算

Tall Building Construction Tower Crane Based on ETABS Calculation

超高层建筑至一定高度,核心筒会采用变截面设计,由剪力墙收缩为柱,因此塔式起重机等大型机械的受力性能对核心筒结构的影响不能忽视。针对实际工程,运用ETABS有限元软件分别建立核心筒收缩前后分析模型,采用最不利工况进行加载,展现施工状态下的塔式起重机对核心筒主体结构的影响,为施工现场提供参考依据。

When the super high-rise building reaches a certain height,the core tube will adopt variable cross-section design,and the shear wall is retracted into a column.Therefore,the impact of the mechanical performance of tower cranes and other large machinery on the core tube structure cannot be ignored.For the actual project,the ETABS finite element software is used to establish the analytical model before and after the core tube is retracted.The most unfavorable working conditions are used for loading.Show the impact of tower cranes on the main structure of the core tube under construction,and provide a reference for the construction site.
