Finite Element Analysis of Anti-Seismic Performance of Flange Connection in Circular-Pipe Tower Structures

Abstract:

For tower structures located in high-intensity seismic zone, despite the importance of anti-seismic performance in flange connection, far less attention has been given to it. Based on finite element analysis results carried by ANSYS software, under pressure and moment, influence of stiffener height and axial compression stress ratio of steel pipe on the anti-seismic performance of flange connection was studied. The main results shows that lower axial compression stress ratio of steel pipe or higher stiffener height would improve the anti-seismic performance of flange connection. And closer flange connection from the end restraint would lead to better anti-seismic performance.
