Abstract: The structural integrity reassessment of old offshore platforms requires advanced nonlinear frame analyses with an accurate representation of local joint responses under overloading conditions. All the existing joint formulations for Circular Hollow Section (CHS) joints remain empirical in nature and lack strong theoretical foundations, which limit their transferability to a wide range of joint geometry, material and loading conditions foreseeable in real offshore platforms. This study aims to develop a theoretical-based joint representation to capture the load-deformation relationship for CHS X- and K-joints under nonlinear deformations and possible unstable fracture failures. The pushover analysis of offshore jackets will implement the proposed joint formulations to investigate the offshore structural behavior under the predominantly static loading condition. The result will allow rational decisions to be made concerning the structural integrity of existing jacket systems.
