STEEL PLATE CONCRETE STRUCTURE, NUCLEAR REACTOR STORAGE VESSEL AND NUCLEAR REACTOR STORAGE VESSEL INSIDE STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To prevent or restrain buckling of steel plates, when exposed to an environment exceeding the ordinary temperature, in a steel plate concrete structure. PSOLUTION: This steel plate concrete structure has the two steel plates 4 mutually oppositely arranged at an interval, a plurality of studs 3 respectively installed on the steel plates 4 on the opposed side of the two steel plates 4 and mutually arranged at a predetermined interval and concrete 2 filled between the two steel plates 4, and has the possibility of exposing at least one of the two steel plates 4 to the environment exceeding the ordinary temperature. Assuming the plate thickness of the high temperature side steel plate 4 to be (t) and a pitch of the studs 3 installed on these steel plates 4 to be B, the ratio B/t of B to (t) is set in a range of 2 to 40.
