Reliability Based Analysis of Berthing Structure Subjected to Variable Crane Load

摘要

The Indian peninsula is also strategically located between the Atlantic Ocean in the west and the Pacific Ocean in the east and Indian Ocean in south, with a 7,517 km-long coastline. During the last decades ships have grown larger in number, as a result consequence berthing facilities have to be adopted for larger units. Over the years, cargo handling capacity of Major Ports has steadily increased. Due to this, Berthing facilities for ships has increased and new berthing structures have to be constructed. Berthing structures are subjected to large lateral forces due to berthing and mooring vessels. The lateral forces are to be resisted by the vertical pile, raker pile and diaphragm wall. The construction and maintenance of Berthing structures are very expensive and therefore the safest and most economical design should be adopted. Many studies have been reported previously on the loading mechanism of laterally loaded pile group on horizontal ground. The Berth is subjected to moving crawler crane load perpendicular to the direction of berth with its designed capacity. This paper aims to study the behavior of berthing structure by using Reliability based analysis when subjected to variable crane load and to determine the member characteristics of each structural component. The software's used are STAAD Pro for modelling of structure and MATLAB for Reliability analysis.
