アンケート調査に基づく建物の非構造部材被害と地震動強さとの関係

抄録

We conducted questionnaire surveys to examine the relation between seismic intensities and damage of various non-structural elements of RC buildings during the 2000 Tottori-ken seibu earthquake and the 2001 Geiyo earthquake. RC buildings near the earthquake observation stations were selected for our surveys. Results of our surveys indicate the following characteristics of damage of non-structural elements of buildings in the areas where the JMA instrumental seismic intensity were less than 6.0. a) Damage was mainly detected in exterior and interior walls, window glasses, ceilings and doors. Air conditioning systems, fire protection systems and elevated equipments were slightly damaged during the earthquakes, b) Many kinds of non-structural elements were damaged in the building at the seismic intensity over 5.0. c) Percentages of buildings damaged at non-structural elements increase with older buildings, d) In many cases, several non-structural elements were simultaneously damaged during the earthquake.
