PROBLEM TO BE SOLVED: To provide a building capable of suppressing an occurrence of a local stress concentration.SOLUTION: A building 10 of steel construction includes a first floor part 11, a second floor part 12, and a third floor part 13. A main frame 31 and an oblique line frame 32 are provided in the third floor part 13. In the oblique line frame 32, an oblique structure plane is formed at upper end positions of columns 33 and columns 41 shorter than the columns 33, and a vertical structure plane is formed between the columns 41 continuously from the lower end of the oblique structure plane. Brace reinforcement parts 46 each having a brace as a reinforcement element are provided in the oblique structure plane, and lattice columns 45 each having an energy absorption part for absorbing energy by yielding due to a load to be plastically deformed are provided in the vertical structure plane. |
