STRUCTURAL STEELWORK AND DESIGN METHOD OF STRUCTURAL STEELWORK
To provide a structural steelwork having an improved earthquake performance compared to a case in which a steel column is formed using steel material with a low yield ratio even if the steel column is formed using the steel material with a high yield ratio at least partially.SOLUTION: A structural steelwork 1 is provided that comprises a steel beam and a steel column 21 formed by steel material having a yield ratio greater than 80% and less than 90% and is configured in a steel frame structure having a plurality of layers 11 in a vertical direction and a column - beam yield strength ratio is greater than or equal to 1.5 or (1) formula is satisfied and a design strength of a column base part 22 used in the layer arranged in most downward in a plurality of layers among the steel material is less than or equal to 0.815 times of a yield strength the steel material.
