Abstract

For steel-concrete composite beams, the stress's re-distribution between steel girder and concrete deck caused by the concrete creep may seriously affect the safety of the bridge, especially for a cable-stayed bridge with composite girder. Based on the effective elastic modular method, an approach for the analysis of the creep effects in the composite girder of a cable-stayed bridge was presented. The particularity of the proposed model relies on its ability to capture the redistribution of internal force and stress caused by creep in composite beam of some complex bridges such as cablestayed bridge, while considering the effect of the loading age of the precast concrete deck.
