ABSTRACT

The article presents studies and numerical simulations on modeling snow influence on TAURON ARENA suspended roof structure in Cracow. The scope of work includes experimental tests, functions solutions taking into account various cases of snow impact according to PN and EC, as well as numerical simulations for the sport and entertainment arena in the Czyzyny district. The FEM roof structure model developed in the SOFISITK software consists of bar and surface elements. The structure is made of bar elements, whereas the facade and the roof slope are made of surface elements. Finite element method meshing is developed using the Coons’ method and four-node elements with six degrees of freedom are applied on each node. The conducted research and numerical analyses allowed for establishing a proper way of snow distribution on the load bearing elements of the structure. The results of the work will act as a guidelines for services dealing with the roof maintenance, and will minimize the risk of a collapse caused by improper snow removal.

Keywords: dynamic analysis, snow load, suspended structure, peripheral bracings
