Abstract
The Hyogoken-Nanbu earthquake struck two power plants in east part of Hyogo-Prefecture. These are large steel structures with ribeted joints designed in conformity with the past criteria. The structures suffered not so severe damage and the damage were watched at some of the braces. We tried to simulate the state of damage based on seismic response analyses and a full scale test of brace joints. Consequently the simulation could express the real damage and the joints would be damaged around the stress calculated by these analyses. In this study it was proved that the analyses were effective.
