【 摘 要 】

This paper in order to study the circular CFST section temperature field distribution was caused by temperature variation, which the temperature change testing under the outdoor environment and artificial climate simulated test chamber, measuring the temperature field of the CFST component and the plain concrete control specimen under different temperature variation conditions. The test results showing that the temperature field of the CFST and the plain concrete is basically same. The cross section temperature fields basically presented uniform distribution when there was no sunshine and under the action of sunshine, the temperature field of the specimen section showed a non-uniform distribution. In both conditions, the specimen section temperature field shows a phenomenon that the temperature change from outside to inside is increasingly lag behind, and the specimen section maximum temperature difference mainly depends on the solar radiation and the range of temperature changes.
