THE CALCULATION METHOD OF LARGE SHIPYARD INDUSTRIAL CONCRETE FLOOR

In order to future understand the mechanical properties and calculation method of large shipyard industrial floor, the application analysis is conducted according to the road engineering multilayer elastic system and elastic foundation. According to the analysis result and mechanical property of floor, the improved multilayer elastic foundation model is put forward, which focuses on the floor block stiffness calculation method and interfacial sliding between floor layers. The numerical simulation results show that different regional block stiffness can adjust the deformation curve; the mechanical performance of floor is close to the plate member by considering interfacial sliding coefficient. The study described in this paper can provide a basis for simple, practical calculation method in future research.
