Steel-concrete composite flyover

Abstract

The Master thesis deals with the design of the main supporting structure (superstructure) of the road bridge, made of four prefabricated composite girders, which simultaneously make formwork for the deck from in-situ concrete. The bridge serves as a flyover above the highway D11. In the thesis will be represented three alternatives of the bridge, such as simply supported beam bridge with one span, simply supported beam bridge with two spans and integral bridge with one span. Because of the large span of 47,6m and limited clearance under the bridge of 5 m, the bridge is designed as an integral construction.The Master thesis deals with the design of the main supporting structure (superstructure) of the road bridge, made of four prefabricated composite girders, which simultaneously make formwork for the deck from in-situ concrete.
