Title of the article | Steel polygonal arch structures from standardized elements |
Abstract. | The main problem in the construction of steel polygonal arches is the design of a reliable nodal connection, both from the point of view of ensuring load-bearing capacity and reducing steel consumption, while the nodal connection must provide the required outline of the arch. The purpose of the work is to develop a nodal connection of standardized elements without flanges, allowing the construction of an arch of arbitrary span and comparison of the design solution in terms of steel consumption with known analogues. The objectives of the study are: consideration of known nodal connections of steel polygonal arches, identification of advantages and disadvantages, development of a new connection and comparison of steel consumption and manufacturing complexity with existing technical solutions. Results. The paper presents the results of studies of nodal connections of steel polygonal arches. As a result, it was revealed that the polygonal arch proposed in this work has the lowest cost in terms of steel consumption: its cost is 7.7% less than the cost of an arch with ring inserts and 19.3% less than the cost of an arch made of the same type of elements. Conclusions. The significance of the results obtained for the construction industry is that due to the direct connection of the standardized elements of polygonal arches, the need for flanges is eliminated, which makes it possible to lighten the load-bearing structure. |
