兵庫県南部地震の地震被害データを用いた建篵詏備の被害率曲線

摘要

The seismic performance of building equipments as well as building frames is one of critical factors to maintain the function of buildings after the occurrence of earthquakes. Therefore, the damage database of building equipments due to 1995 Hyogoken Nanbu earthquake is investigated to evaluate the seismic performance of building equipments from the statistical point. The damage occurrence is modeled by the binomial distribution, and the damage ratio curves, the shape of which is assumed to be the lognormal distribution, are calculated through the maximum likelihood method. It is evaluated that the differences of the building year, the structural type and the building story influence on the median of damage ratio curves. Moreover, the damage ratio curves are evaluated through the response acceleration and the response story deformation angle in order to compare the build code of equipments.%最近、事業継続計画（BCP）が注目され、地震後においても重要 業務はできる限り継続させることが求められており、建物の機能性 が重要になっている。しかし、最近の地震被害を見ると、建物被害 のみならず、天井の落下、窓ガラスの破損、エレベータの停止など、 非構造部材や建築設備の被害事例が報告されている。
