Abstract: Berthing structure is a general term used to describe a marine structure for the mooring of vessels, for loading and unloading cargo, for embarking and disembarking passengers. Damage to port/harbor structure was primarily due to Stack and Crane load. Berthing structure mainly consists of Deck slab and Substructure. Substructure is a part of a structure which helps in transferring the load of the superstructure and its own load on to the supporting soil. Forces and moments acting on the superstructure were transfer to the substructure elements In this paper, considered the entire superstructure is situated on Substructure consists of vertical piles, racker piles & Diaphragm wall to withstand loading conditions i.e., BGML, Crane load, Stack load, Concentrated load& IRC 70R loadings. In addition to these loads it can also subjected to mooring forces. The literature on the adequacy of the STAAD.Pro modeling of substructure to analyze their behavior under varying the Stack, Crane & Mooring forces is limited. . This paper describes the influence of Stack, Crane and Mooring forces on bending moment of “T” Shaped Diaphragm wall and the axial forces of vertical & racker piles.

Keywords: SubStructure, Stack Load, Crane Load and Mooring Load
