日本是一个多地震的国家,为使建筑结构达到能抗御地震的目的,其木结构、钢结构以及劲性钢筋混凝土结构占有很大比例。但近几年来,由于钢筋混凝土结构抗震研究的发展,再加上其造价远比钢结构经济,并具有较好的物理性能等特点,在日本的住宅建设中开始得到广泛的应用。日本对于高层钢筋混凝土住宅的设计研究,是在1969年由鹿岛建设公司首先开始的。他们建造的第一座钢筋混凝土框架结构的高层住宅,名为榫名町公寓,高度为48米,16层,矩形平面。随后,又在东京
Japan is a country with many earthquakes. In order to make the building structure resistant to earthquakes, its wood structure, steel structure, and reinforced concrete structure occupy a large proportion. However, in recent years, due to the development of seismic research of reinforced concrete structures, coupled with its cost far more economic than that of steel structures, and having good physical properties, it has begun to find wide application in housing construction in Japan. Japan’s design research on high-rise reinforced concrete houses was first started by the Kashima Construction Company in 1969. The first high-rise residential building with a reinforced concrete frame structure built by them was named Futanicho Apartment. The height is 48 meters and 16 floors, and the rectangular plane. Subsequently, in Tokyo
