Design features of bimetallic bridges

Abstract

The Design and construction of metal bridges is the most reasonable from the structural and technological point of view, as well as from the standpoint of the implementation of non-standard engineering and spatial solutions. The weak point most often in this case is the efficiency of construction. To improve economic efficiency, it is recommended to use metal structures, the most loaded elements of the beams in which should be made of high-strength steels, and all other conventional rolled steel. Spans of a continuous plate should be designed in such a way that the spans moments are equal. The authors propose to assign the values of spans in accordance with their effective ratio and design the span structure of the three types of standard blocks.
