title = "Nonlinear modelling of weld-beaded composite tubular connections",
abstract = "A newly developed nonlinear model for the analysis of composite tubular connections with weld-beads, typically used in fixed offshore platforms, is presented. The constitutive relationship used is based on a semi-empirical approach making use of load-slip curves obtained from experiments conducted by the authors, and incorporating simple physical models for the observed failure modes. Comparative studies are undertaken using experimental data and design code predictions from the UK Department of Energy and the American Pertroleum Institute guidance notes. The formulation developed is shown to give results in good agreement with the experimental results. It also gives more consistent results than the available design recommendations.",

note = "Funding Information: The integrity of the composite connections between steel jacket offshore platforms and the foundation piles (Figure 1) is indispensable for the safety and stability of the whole structure. This emphasises the case for safe design procedures. On the other hand, the length of the connection has a strong influence on the weight of the structure, thus emphasising the case for economy. Consequently, optimal design procedures based on a comprehensive understanding of the fundamental load-transfer and failure mechanisms are required. Previous studies I have identified some limitations of existing design recommerldations 2'3. Therefore, a comprehensive study, funded by the Marine Technology Directorate, the UK Department of Energy and some oil companies, was inititated at Imperial College in 1985, covering experimental, analytical and numerical studies of the behaviour of weld-beaded grouted connections. This paper is a continuation of previous research work at Imperial College on plain and prestressed connections.",
