Effect of earthquake directional uncertainty on the seismic response of jacket-type offshore platform
In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...
متن کاملSeismic Response of a Platform-Frame System with Steel Columns
Timber platform-frame shear walls are characterized by high ductility and diffuse energy dissipation but limited in-plane shear resistance. A novel lightweight constructive system composed of steel columns braced with oriented strand board (OSB) panels was conceived and tested. Preliminary laboratory tests were performed to study the OSB-to-column connections with self-drilling screws. Then, th...
متن کاملSeismic Vulnerability Assesment of Jacket Type Offshore Platforms
Most of oil and gas offshore platforms are located in the seismic regains. So, Seismic vulnerability evaluation of the offshore platforms is one of the most important and vital issues in the structural systems. In this study, jacket type offshore platforms are studied by incorporating the pushover analyses and nonlinear time history analyses, in such a way that, first some push over analyses ar...
متن کاملSimple Pile-Soil Interaction Effect on Seismic Response of Fixed Offshore Platforms
In this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. InducedSeismic force is one of the most important excitations for the dynamic response of an offshore structure. According to API, Seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...
متن کاملSeismic Behavior of Jacket Offshore Platform Subjected to Near and Far Field Ground Motions
Offshore structures such as jacket platforms have to inevitably be designed against sever environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...
