This paper studies the relation between structural damage of reinforced concrete buildings and ground motion intensity during the 1995 Hyogoken-Nanbu earthquake. We have used two surveyed data for damaged schools and mid-to-high-rise buildings which list description of buildings, structural damage degree, and seismic performance indices. Buildings are classified and their damage are regressed by construction years, seismic performance indices, number of floors, and peak ground velocities based on tree based model. Obtained regression and classification trees show how the effects of ground motion intensity on building damage vary with the seismic performance of the building, damage degree, and peak ground velocities.
