シェル・空間構造の防災研究

Abstract

建築構造に用いられるシェル・空間構造の防災研究は個々の形態、構法により、耐震、耐風、耐雪、耐火の諸方面からなされねばならず、筆者は耐火問題を除いて種々研究を遂行してきた。ここでは、特に球形シェル及び屋根型円筒シェルの地震応答に関する一連の研究を概説する。

Safety of shells and spatial structures is especially necessary, because the scale of these structures is usually large and large number of people are contained. The author has been engaged in the research of shells and spatial structures for several ten years from the viewpoint of safety security for the natural disaster.At the factor of the natural disaster, there are earthquakes, wind, snows, etc.. One of thses disaster factor should be taken into consideration according to the shape and structural characteristics of these structures in disaster prevention research. Here, a part of the authours research concerning earthquake response of spherical domes and roof type cylindrical shells is summarized. And how these researches are promoted is shown.
