Optimization of the design of bridge intermediate supports

Abstract

This scientific article covers issues of improving the intermediate supports of bridges. The design features of existing monolithic supports were analyzed, and existing shortcomings in terms of their shape, dimensions, and material consumption were identified. Three design options based on monolithic reinforced concrete have been proposed, and their seismic resistance, load-bearing capacity, and economic efficiency have been parametrically compared. It has been proven that the second proposed structural variant is the most optimal solution in terms of material consumption, economic indicators, and seismic resistance. The research results provide scientifically based recommendations for practical application in improving bridge intermediate supports.
