In previous studies we have established a set of dynamic models of reinforced concrete (RC) buildings and wooden houses for damage evaluation based on the damage statistics in Kobe surveyed after the 1995 Hyogo-ken Nanbu earthquake and nonlinear response analyses for synthetic waveforms simulated by Matsushima and Kawase (2000). In this paper, we proceed to construct a set of dynamic models of steel buildings for damage evaluation. In the process of establishing models we found that strengths of steel buildings are not so much different from those considered in the building code. This implies that the strengths of steel buildings are not influenced strongly by other factors not considered in design such as non-structural partitioning walls. Damage ratio distributions derived from established models show similar pattern to the observed ones though calculated damage ratios are distributed wider than the observed. By using steel building models established here with the models for reinforced concrete buildings and wooden houses already established, we can predict the whole picture of urban seismic disasters.
