Linear and Non-Linear Static Analysis of Berthing Structure

Rapid growth in the water transport system demands the construction of more port and harbour structures.Berthing structures are constructed in ports and harbours to provide facilities such as berthing and mooring of vessels, loading and unloading of cargo and embarking and disembarking of passengers. Quays, wharfs, piers, jetties and dolphins are the most widely used berthing structures. In this project, linear and non-linear static analysis berthing structure module is studied. The basic data influence factors which affected the berthing structure were taken into consideration, such as soil characteristics of the proposed location, environmental conditions and range of traffic which will be used in the project is generally taken from Visakhapatnam port. The entire Berth length is 506.4m which is divided into 10 modules and each module length is 50.640m and width of the berth is 33.450m. The Berth has been analyzed by using STAAD Pro Software. After performing the linear and non-linear static analysis of the berthing structure module the behaviour of the structural elements is compared by various parameters deflection, bending moments, shear forces of cross beam, long beam, crane beam, front crane beam, retaining beam and also for the different piles. The axial forces variations of different piles are also studied.

Improved Analysis on Main Beam of the Double-Beam Crane

The double-beam crane main beam by a wide variety of steel welded, the structure is very complex. There are some problems that cause main beam deformation, such as the thin structure, needs to be improved. This paper combined with the finite element model of plate and beam to solve analytical challenges. Determine the dynamic load impact factor, the finite element analysis of the double-beam crane box-type structure of main beam, on the basis of the above, and the main beam finite element computer simulation reinforcement of the four program design and to compare. The strength of the best programs 38.7% higher than the original beam and stiffness 33.9% higher than the original beam.
