Seismic response test of steel frame structure subjected to scenario earthquakes

Shaking table tests on the seismic behavior of a steel frame structure model were performed. The purpose of this test is to estimate the effect of a near-fault ground motion and the scenario earthquake based on the probabilistic seismic hazard analysis on the nuclear power plant structures. Three kinds of earthquake ground motions which represent the design earthquake ground motion for the Korean nuclear power plants, the scenario earthquakes for the Korean nuclear power plant sites and the near-fault earthquake record from the Chi-Chi earthquake were used as the input motion. A 4-story steel frame structure was fabricated to perform the tests
