Study on the assessment of axial crushing force of bulbous bow for bridge against ship collision

The present paper aims to figure out a reasonable simplified method to predict the crushing force of ship bow, which could be used for the risk safety assessment of bridge against ship collision. Two types of ship bow structures with transverse plates and longitudinal stiffeners were tested under axial compressive load. Base on rigid plastic theory, the intersection unit method (IUM) including L-, T- and X-type elements is applied to calculate the crushing force of ship bow structures. For considering longitudinal stiffener, the equivalent thickness method is used to modify IUM. The crushing forces and the total absorbed energies obtained by the developed analytical methods are compared with those in the tests and FE (finite element) analysis. The corresponding experimental results are used to verify the FE modelling technology and developed simplified formulae for the assessment of crushing force for ship bow structures. The accuracy and applicability of the developed simplified formulae are discussed in details.
