Aseismic reliability analysis approach for offshore jacket platform structures

By means of nonlinear pushover collapse analysis approach, the aseismic rel iability analyses of two offshore jacket platforms in the Bohai Gulf in Chi na are studied according to their ocean location and environmental loadings there. On the basis of those analyses, an aseismic reliability analysis ap proach is presented. The results show that the aseismic reliability of thos e platforms is high. Also it is proved that this aseismic reliability analy sis approach is simple, practical and reliable.
