Description:
The paper deals with the identification of the optimal forms of arch span structures of bridges in terms of minimizing the expansion in their foundations. The calculations of thrust at different ratio boom lift for stairs in various arch design schemes (fully articulated, two-hinged, and hingeless arches). A graph of the dependence of the thrust on the ratio of the rise to the span for the bridge reinforced concrete arch, on the basis of which one can choose the most effective ratio of the boom to span for a particular case. A comparison of the distribution of the spread value for multi-span arch bridges with a constant and variable span width is performed. It is concluded that such ratio of the magnitudes of spans is the most effective for the equalization of forces, transmitted to the foundations of the arches of multispan bridges.
