Kind Code:

To provide a frame structure having a megastructure excellent in aseismatic prperty.

In a frame structure 10 provided with a pair of columns 16, 16 and a truss frame structure 18 laterally surported between these columns, an axial yielding part 30 having a smaller sectional area than other parts of the lower chord member 22 between the column 16 and a strut member 26A nearest to the column is formed and it is constituted to bring an axial yielding state prior to the bending hinge of the column 16 when a specified earthquake force occurs. In this way, a form close to a beam yield prior shape can be taken and its collapse mechanism forms the whole collapse configuration and hence the aseismatic property can be improved.
