Modelling of lamellar breathing effect
Original language description
This paper presents approaches of modelling of the lamellar flanges breathing effect. Such phenomenon may arise on long-span steel or composite RC concrete - steel bridges where it is necessary to utilize very thick lamellas that cannot be milled at once. Under the traffic load these structural elements may exhibit vibrations creating moise and high cyclic loading in the corresponding welds. Presented paper addresses modelling technique of the lamellar flanges including the air pocket locked between theflange plates. It addresses the influence of this air on the lamella stiffness and also investigates the influence of the contact between the lamellas. For the modelling is used the well-known finite element method including contact elements amended bythe authors original algorithm calculating the air pocket stiffness influence using the ideal gas equation of state. Calculations are made in the software package ANSYS and using the programing language Python.
