仿生树状钢结构柱设计研究

Research on Design of Dendritic Columns in Bionic Steel Structures

首先阐述了树状柱结构在国内外建筑结构中的应用状况,然后分别对树梢有无支撑的树状柱杆件的计算长度系数取值、树状结构传力路径以及分枝数量进行了论述,并给出了相应的分析结果与设计参数建议。最后,通过实际的树状柱设计工程实例,结合前述理论分析原理,给出了树状柱的设计计算结果及设计中的关键问题,并且进行了相应的分析总结,为空间钢结构采用树状柱结构形式提供了参考。

The application status of dendritic columns in building structures at domestic and abroad was introduced. The effective length, transfer path of force and the branch number of dendritic, columns was discussed respectively for the treetop braced or not. Some suggestions of reasonable grade bracing in dendritic columns and the corresponding design parameters were given. Finally, through an actual design project example, the calculation results and key points of the dendritic column design process were presented. The corresponding analysis and design experiences of dendritic columns were listed as the reference.
