| Abstract | The main target of this work deals with the investigation of the dynamic behavior of offshore platform structure to the torsional load which produces from two ships collision load in opposite direction considering the impact of soil size domain. The ABAQUS software is employed to achieve the structural response considering soil-pile-offshore platform interaction. Two soil models are adopted in this study and these models are elastic model and elastoplastic model, while this study adopted six soil size domains as a function of pile diameter and these sizes are (4D,6D,8D,10D,12D,14D) where D represent pile diameter. The investigation includes pile response and can be described by displacement, twist angle, shear force, bending moment, and shear stress. Also, the displacement of deck slab variation with time is investigated. The investigation illustrates that always the response of piles which comprises displacement, twist angle, shear force, bending moment and shear stress is higher when the pile foundation embedded in elastoplastic soil as compared with elastic soil, also the variation in deck slab response is higher when the pile foundation embedded in elastoplastic soil as compared with elastic soil. It is evident from the result as the soil domain size increases the response of piles and deck slab decrease regardless of the soil model. |
