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.
