    摘要： The present invention allows to inhibit antiplane deformation of steel plates due to the back pressure generated by water content of the concrete, and allows observation of the concrete during a service period.
    In a steel concrete structure including an inner steel plate exposed to a high temperature environment, an outer steel plate, studs and concrete, a steam discharging pipe and a pipe opening are provided. The steam discharging pipe includes small openings. Water content inside the concrete evaporates in a state the temperature of the concrete reaches approximately 100°C, becomes steam, is concentrated in the vicinity of the rear surface of the steel plate, and is discharged to the outside of a containment vessel from the small openings through the steam discharging pipe.
