Abstract
The semi-analytical method for solving structural noise of viaduct box beam is actively investigated in this study. A semi-analytical method with satisfactory computation effectiveness and precision is presented in the paper for solving the acoustic radiation from an infinite concrete viaduct box beam in the air. The method is based on the theory of the extended homogeneous capacity high precision integration method and the spectrum method of virtual boundary with a complex radius vector. The semi-analytical solution is obtained through the Fourier transformation (FT) and stationary phase method. It's very significant for further understanding the acoustic radiation characteristic of the urban viaduct box beam from qualitative analysis. Also, this study has the value of noise controlling and forecasting for building and optimization designing for box beam.
