Abstract

Abstract

According to the project requirements of HTR-PM600, the single-sided fire resistance test of double-steel-plate concrete shear wall (SC shear wall) structure in nuclear power plant was carried out. Based on the single-sided ISO834 standard fire test of 4 typical specimens under the same axial compression ratio, the effects of wall thickness of SC shear wall, the thickness of steel plates on otherside, tie rod structure, etc. on the thermal insulation property of specimens were analyzed and compared. The temperature field distribution across the cross section, vertical deformation, damage mode, fire resistance, etc. of the SC shear walls subjected to sigle-sided fire exposure were ascertained. The test results showed that the steel plates on the fire surface of the four SC shear wall specimens were slightly damaged, but the steel plates on the back fire surface were basically intact. The total thickness of shear wall section had a significant effect on the fire resistance of one side under fire condition, and the thickness of outer steel plate on fire side also had a certain effect on the temperature difference between the furnace temperature and the concrete on fire surface. SC shear wall structure had good vertical bearing capacity and fire resistance under large temperature difference on both sides.
