Abstract

A 9-story steel frame reinforced concrete building in Sendai was severely damaged during the 2011 Great East Japan Earthquake. Fortunately, two seismometers were emplaced at the 1^stfloor and the 9^thfloor, and the whole earthquake records were observed during this earthquake. The nonlinear response analysis of the building is simulated which based on the elastic plastic properties of constituent structural elements during the earthquake. And a partial uplift phenomenon between the 2^ndfloor and the 3^rdfloor which observed is confirmed by the simulation analysis.
