The brace configuration plays an important role to the ultimate strength of fixed jacket platform. The braces against the combined load in vertical and horizontal direction. In the present study, the ultimate strength of the fixed jacket platform is analysed considering the shape of the structural geometric. Four types of brace configuration namely, K, N, X and Y are taken to be assessed. Dimensions of the structure are constant including properties and materials. The boundary conditions are assumed to be fixed at the bottom part. The Non-Linear Finite Element Analysis (NLFEA) is adopted to calculate the ultimate strength of the structure and those results of brace configuration are compared with one another and discussed in the present study.

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.
