Abstract:n recent years, the possibility of using hollow structural steel (HSS) columns filled with self-consolidating concrete (SCC) in practical engineering, has been the interests of structural engineers. However, the composite members are susceptible to the characteristics of temperature field due to cement hydration heat, the shrinkage of core concrete and the deformations subjected to long-term loading. The temperature field during cement hydration, and the shrinkage of the concrete core in self-consolidating concrete (SCC)-filled hollow structural steel (HSS) tubes (SCCHSS) are experimentally studied in this paper. The main parameters are sectional dimensions and sectional types. The observed results illustrate that the characteristics of the temperature field in SCCHSS tubes is similar to that of normal concrete members. However, the shrinkage value of the concrete core in SCCHSS tubes is significantly smaller than that of normal concrete. Based on the measured results, shrinkage mode | |||
