This paper introduces a novel eccentric jacket substructure for offshore wind turbines, engineered to withstand severe environmental forces and provide a robust alternative to conventional X-braced jackets in seismically active regions. The design features fully overlapped joints at all connections, comprising a chord and two braces arranged within a single plane. The cyclic behavior of these joints is analyzed using nonlinear finite element (FE) modeling, calibrated and validated against experimental results. The study demonstrates that while the geometric parameters of the chord member and through brace (βCT, τCT, γC) have insignificant impact, those of the through brace and lap brace (βTL, τTL, γT) significantly influence joint performance under axial cyclic loading of the lap brace. A marked reduction in load-bearing and energy dissipation capacity is observed following lap brace yielding and local buckling. To enhance performance, it is suggested that the dissipative zone for fully overlapped tubular joints subjected to cyclic loading should be located in the short link segment of the through brace connected to the chord member.
