Abstract
In this paper some works on the seismic aspects of
completely overlap tubular joints were presented. This type
of joint configuration can be found in a kind of innovative
offshore jacket configuration called eccentric jacket. In this
paper, the design concepts for eccentric jacket were
described. Some advantages of the completely overlap joint
were proposed from the viewpoint of seismic resistance
design. Then some quantitive indictors used in onshore
industry to characterize the seismic performance of
completely overlap joints were examined. Finally, a
numerical analysis was carried out to simulate the inelastic
behavior of the joint under cyclic loads. The hysteresis curve
was analyzed to evaluate the seismic performance of the
joint.
