タイトル(和): 鉄筋コンクリート造学校校舎の耐震診断指標値と被災度
抄録(和): 1995年兵庫県南部地震で被害調査を行った鉄筋コンクリート造学校建築について、耐震診断基準にしたがって構造耐震指標を算出した。調査対象約700棟のうち、105棟について耐震1次診断を、75棟について耐震2次診断を行い、構造耐震指標と被災度判定基準による損傷割合による被災度を比較した。構造物耐震指標が大きいと被災度は小さい傾向があり、耐震性能を評価する指標として概ね妥当であることが検証された。構造耐震指標が0.4以下では多くの建物が大破となり、0.4〜0.6では中破程度、0.6程度以上の建物での被害はほぼ小破以下の被害にとどまった。ただし、構造耐震指標が0.6より大きい建物でも強度指標が比較的低く靭性指標が大きい建物では被害の程度が大きい場合もあった。

タイトル(英): SEISMIC PERFORMANCE INDICES AND OBSERVED DAMAGES OF REINFORCED CONCRETE SCHOOL BUILDINGS
抄録(英): Seismic performance indices were evaluated for reinforced concrete school buildings, damages of which were observed after 1995 Hyogo-ken Nanbu Earthquake. The method of evaluation was based on "Standards for seismic performance evaluation of existing reinforced concrete buildings." The first seismic performance indices (Is1) were calculated for a total of 105 buildings out of 700 surveyed. The second seismic performance indices (Is2) were evaluated for 74 buildings out of 105. A fair correlation was observed between the calculated performance indices and the damage indices. Most of the buildings, Is2 values of which were less than 0.4, were nearly collapsed or severely damaged. The buildings with Is2 of 0.4 through 0.6 were moderately damaged or more. Most with Is2 higher than 0.6 suffered minor or less damages, except for several buildings which were classified into near collapse, because they attained large displacement due to relatively low strength although they had adequate deformation capacity.
