Abstract: Steel concrete composite construction segment is one of the key technologies critical hybrid girder cable-stayed bridge, it is designed to directly affect the safety and durability of the bridge, a key segment of steel concrete composite structure has been much research in the world bridge sector is concerned. In this paper, simulation analysis and large scale model test are carried out to simulate the mechanical behavior of steel concrete composite section. To provide a research method of the stress mechanism, the transfer path and the way of the stress and the corresponding reasonable structure of the combined segment.
