This paper aims at discussing an approach which can be used to demonstrate enhanced structural performance due to both the presence and lack of grouted piles. In this study, nonlinear fiber element will be used. Therefore, different behavior of grouted and ungrouted jackets and the relative different pile-leg interaction is investigated. The experimental results of two frames of the same geometries filled with a standard offshore cement grout in their pile-leg gap under lateral deck displacement-controlled load, together with the two similar frames without any grout, are ongoing and will be presented in near future. However, this paper presents an important comparison between the general behaviors of grouted and un-grouted offshore frames in an area where there are many existing jacket-type platforms.
