A Study for the Long Term Behavior of Steel-Concrete Composite Members Considering the Creep and Shrinkage |
| Abstract |
In this study, analytical methods for predictiong the long term behavior of steel-concrete composite structures due to creep and shrinkage of concrete are investigated.For structural analysis considering long term behavior, the results are much dependent on the predictive models for creep and shrinkage of concrete which are ACI model,CEB-FIP(90) model, and BP-KX model and the methods for the time analysis of structures which are AEMM, RCM and IDM. To demonstrate the validity of the program which was developed for this study, a steel-concrete composite column subjected to constant axial deformation(relaxation) and axial creep were tested, and the experimental results were compared with analytical results.It was found that stresses are redistributed between concrete and wide flange steel, and analytical results by ACI model, BP-KX model well predict the experimental data. |
