Ring Stiffener

At present, the round steel pipe section is used more often in the transmission tower. This paper introduces the strengthening measures to the steel pipe node, which shows that ring-stiffener is a kind of very good strengthening measure. Then it is focus on the research of ultimate bearing capacity of the space type KK-intersecting nodes by the ANSYS finite element analysis software. Try to find the differences between the node with ring-stiffener and without ring-stiffener. Get the conclusions through the analysis and comparison, and provide a reference for practical engineering.

Flange Connection

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.

Element Analysis

The project intends to construct steel pipe piles on both sides of trestle wharf, and the soil vibrations caused by piling construction might have an important effect on the safe service of wharf. In this paper, the dynamic signals during piling construction were recorded and recognized by NExT-ERA. Meanwhile, modal analysis through finite element model of wharf was performed. Through a comparative analysis of the two results, the first two orders of frequency for wharf were obtained. The results would lay foundation for further analysis of dynamic responses of wharf when pile locations close to wharf.
