    摘要:

    声屏障柱脚结构一般采用锚栓连接钢立柱与混凝土基础。此类节点受力方式既不同于钢筋混凝土结构,亦不同于钢结构的螺栓群连接,而钢结构相关设计规范和混凝土设计规范中均未给出此类节点结构受力分析计算办法。本文在轨道交通声屏障柱脚锚栓连接节点结构受力分析中,提出按平截面假定方法分析的计算原理,结合在上海申通地铁集团有限公司科研项目《声屏障风荷载特性研究》中得出的风荷载作用数值,按照计算原理得出的方法,计算了六种不同荷载组合下的柱脚节点受力,并采用有限元仿真分析并行计算,对比二者计算结果以验证该原理和方法,可供相关设计人员计算参考。

    Abstract:

    The column base structure of the sound barrier generally adopts anchor bolt connections between the steel column and the concrete foundation. The load-bearing mode of this type of joint is different from both the reinforcement concrete structure and the bolt group connections of steel structures. However, neither the steel structure design specifications nor the concrete design specifications provide methods for analyzing and calculating the load-bearing of such joint structures. The calculation principle of analyzing the load-bearing of the anchor bolt connection joint structure at the column foot of the rail transit sound barrier is proposed according to the plane cross-section assumption method. Combined with the wind load values obtained from the Study on Wind Load Characteristics of Sound Barrier in the scientific research project of Shanghai Shentong Metro Group Co., Ltd., the load-bearing of the column foot joint under six different load combinations is calculated according to the method of calculation principle. The finite element simulation analysis is used for its calculation. Compared with the calculation results of the both, the principle and method are verified, which provides the reference for relevant design personnel.
