Description
Summary:Jacket platform is one of the offshore structure where the pile is fixed at the bottom sea level. Pile and brace configuration has a significant influence on local and global structural strength under axial and lateral loads. Pile is one of the most important elements for the fixed offshore structure. On the other hand, the pile is also very critical to resists not only axial compression but also lateral pressure. The objective of the present study is to analyzed pile deflection due to asymmetrically distribution loads. The numerical calculation is used to analyze pile deflection due to asymmetrically distribution loads. In this case, large deflection analysis is separated into two asymmetrically loading conditions those are trapezoidal and triangular with different end support. The result obtained by numerical analysis is therefore compared with the analytical solution using direct integration. It found that the pile deflection obtained by numerical analysis is almost identic with direct integration. It is also observed that the end support condition gives significant influence to support reaction and deflection.
