Abstract: PROBLEM TO BE SOLVED: To attain cost reduction by dividing steel plate which forms a steel plate concrete structure into a plurality of sections, and connecting the steel plates of adjacent sections to each other through a tension material, such as a wire. SOLUTION: A heat-resisting steel plate concrete structure is constituted of a steel plate 1, and a concrete 2 which is integrated with the steel plate 1 through a number of studs 3 formed so as to be protruded on the plate surface of the steel plate 1. The steel plate 1 is divided into a plurality of sections, the steel plates 1 of the adjacent sections are connected through tension materials 4, such as a number of wires formed with a space provided between each other, and the spaced part between the steel plates 1 of the adjacent sections is filled with fire resistant rubber 5. When tensile stress acts on the steel plate 1, the steel plate 1 and the tension members 4 undertake tensile force, and on the other hand, the concrete 2 receives compressive force.  When compressive pressure acts on the steel plate 1, the tension material 4 and fire resistant rubber 5 make out-of-plane deformation toward outside. It is thus possible to prevent generation of cracks in the concrete, and buckling in the steel plate.
