**4.2 Features by category**

In terms of structural types, among the 18 cases of steel frame structures, 11% were classified as red, 50% as yellow, and 39% as green. Among the 26 cases focused on reinforced concrete structures, 4% were classified as red, 58% as yellow, and 38% as green. As for the wooden structures, out of the 7 cases, 29% were classified as red, 14% as yellow, 29% as green, and 29% as collapse.

Furthermore, focusing on the aggregation based on the ratio between the probabilistic seismic velocity from JSHIS and the S-wave velocity (Vs), when dividing it by the average, the results showed that for cases below the average, 68% were classified as green and 32% as yellow. On the other hand, for cases above the average, 70% were classified as yellow, 22% as red, and 8% as collapse, confirming the dependence on ground characteristics (**Table 6**).
