都市における建築構造物の地震被害推定に関する基礎的研究(1)-木造構造物の地震応答推定-

Abstract

It is very important to estimate seismic hazard of building structures in urban area when con-sidering total anti-seismic safety of the city. However on this occasion, there are many factors toconsider such as parameters of earthquake, soil condition and structures. In this study, the prob-lems to be studyed were drawn and arranged from the points of view of input wave, dynamiccharacteristics of structure and criteria of seismic hazard estimation. Next, as the first step ofconstructing seismic hazard estimation method for structures, simulation analysis was performedin order to clear the earthquake response characteristics of various types of wooden houses.Analysis shows that the response of wooden houses is fairly affected by the frequency character-istics of input wave and that of structures, but the response is highly correlated with the max-imum velocity of input wave. Accordingly, a simple expression for estimating the response ofwooden houses was derived and response estimation of wooden houses in kyoto city was per-formed using this relation.
