Influence of nonstructural members on seismic performance of steel structures: An application to the thermal power station building

A proposal for the business continuity was contributed, that a steel-frame building is to be maintained in an elastic state during an earthquake. Nonstructural members which had not be evaluated as a proof stress, sometimes influence the seismic performance of buildings. The shear histories of nonstructural members were grasped by the frame experiments with the nonstructural members. And the response analysis was carried out, that was assumed the steel-frame thermal power station building just above the focus of a M6.9 earthquake, considering the shear histories of nonstructural members. The RC nonstructural wall shows high first modulus of elasticity and brittleness. And it is confirmed that the steel structural members of the thermal power station building which would be thought to show plasticity, approximately fitted into the elastic state by considering the RC nonstructural walls.
