Analysis of the Wind Vibration Response of Suspension Cable Crossing Pipeline

摘要

Taking the spanning pipeline of Wei-Hui engineering project as an example, spatial correlation of wind field simulation program is compiled by using MATLAB. As a result, the Power spectral density function for simulation of the wind speed is in good agreement with the target power spectrum. That means this method has relatively-high accuracy. Converting the wind speed into wind load and imposing onto the finite element model of suspension cable crossing pipeline, vibration response analysis is made. The structure displacement, acceleration time history curve and the stress distribution of the components are obtained. The results show that the suspension cable crossing pipeline structures under wind load are safe. And this analysis also provides a reference for the other wind resistant design of similar structure.
