Abstrait:

The shrinkage and creep effects of concrete is an indispensable calculation content in the design of concrete bridges and composite bridges. Based on past experience, the deformation of concrete slabs is constrained by steel plate. As a special concrete material, the shrinkage and creep mechanism of UHPC is similar to that of ordinary concrete. However, the shrinkage and creep rate of UHPC is different. This paper mainly calculates and analyses the shrinkage and creep effects of steel-concrete-UHPC composite slabs under two different construction conditions (cantilever construction and full framing construction). Firstly, the solid finite element method is used to simulate the shrinkage and creep effects of composite slabs. Then, the stress and deformation of each component in the composite slabs under the two construction conditions are compared and analysed. Finally, the influence of construction methods on the shrinkage and creep performance of the steel-concrete-UHPC composite slabs is revealed and summarized.
