A STUDY OF THE RESOURSE OF BEARING CAPACITY OF THE LARGE-SPAN ROOF OF A STADIUM MADE OF ORTHOGONAL METAL TRUSSES
Based on an overview of the roof systems of football stadiums, a structural system of a large-span roof made of orthogonal 2-D metal trusses was developed. A computer analysis of bearing capacity of the roof was performed under the assumption of the abnormal increase of the snow load.It has been dem...

| description | Based on an overview of the roof systems of football stadiums, a structural system of a large-span roof made of orthogonal 2-D metal trusses was developed. A computer analysis of bearing capacity of the roof was performed under the assumption of the abnormal increase of the snow load.It has been demonstrated that a limited number of additionally installed metal bars can significantly increase the bearing capacity of the roof. The role of these bars is to reduce the effective length of the most loaded elements of the grid of metal trusses for in-plane and out-of-plane buckling.The limit values of snow load for consecutive steps of reinforcement are established, and the effect of the added bars on the bearing capacity of the roof structure is estimated.The results of the investigation are presented in the form of drawings and diagrams. Conclusions are made on the resource of the load-bearing capacity of the large-span roof of the stadium made of 2-D orthogonal trusses. |
