The finite element analysis method of tall and flexibility attachment structure

随着建筑业的迅猛发展,建筑物日益高耸化,塔机起重机、施工升降机等建筑施工设备的作业高度也随之增高。为了保证设备结构的稳定性,要对塔式起重机和施工升降机的塔身增设必要的附加支撑,从而形成高耸附着结构。由于附加支撑依赖于现场情况,附着结构的形式和布置各式各样,目前在起重机械相关规范中为高耸附着施工机械结构提供的计算方法和理论很不充分1,2,传统的计算也往往采用简化近似公式3或将附加支撑视为刚性4。文献5

对国内外常用塔身附着刚度的计算方法进行了研究,文献6探索了格构式构件等效为实腹式构件的方法,这些工作为建立更加准确的多跨柔性支撑高耸结构计算模型奠定了基础。
