摘要
大跨度张弦梁结构性能优越,在工程中得到广泛应用。结合一种具有涌泉造型的车辐式张弦结构,利用Rhino软件中的Grasshopper插件进行曲梁建模,采用Catenary运算器确定索形,有效提高了建模速度。考虑结构的最不利工况与初始缺陷的影响,对结构进行了静力分析、动力特性分析、整体稳定计算和抗连续倒塌分析,计算结果满足相关规范标准要求。在车辐结构周边设置采用人字形支撑,通过关节轴承节点实现与主体结构的连接,对主体结构适应性较强。最后,提出对车辐式张弦结构的设计建议,可供类似工程参考。
Long-span beam string structure with superior performance is widely used in engineering.A spoke string structure with spring shape is used.The Grasshopper plug-in in Rhino software is used to model the curved beam,and the Catenary calculator is used to determine the cable shape,which effectively improves the modeling speed.Considering the influence of the most unfavorable working conditions and initial defects of the structure,the static analysis,dynamic characteristic analysis,overall stability calculation and progressive collapse resistance analysis of the structure are carried out.The calculation results meet the requirements of relevant standards.The connection between the joint bearing node and the main structure is realized by using the font support around the spoke structure,which has strong adaptability to the main structure.Finally,the design suggestions for the spoke string structure are proposed,which can be referred for similar projects.
