为适应我国大中城市中高层和超高层建筑的发展,改变在高层建筑中单一采用钢筋混凝土结构的现状,在建筑结构方面,开拓采用钢结构和型钢-钢筋混凝土结构(这类结构日本称为钢骨钢筋混凝土结构,苏联称为劲性混凝土结构,我们简称为钢混结构,下同)是当前面临的新课题。建国三十多年来,由于钢材紧缺,城市建筑高度受到经济条件的限制,因此在1984年以前,我国尚无新建的高层钢结构建筑。随着对外开放和对内搞活的政策的执行,与国外合资工程日益增多,又由于城市人口大
In order to adapt to the development of middle and high-rise and super high-rise buildings in large and medium-sized cities in China, the status quo of single-use reinforced concrete structures in high-rise buildings has been changed. In terms of building structures, steel structures and steel-reinforced concrete structures have been exploited. The steel-reinforced concrete structure, the Soviet Union’s name for a stiff concrete structure, we will call it simply a steel-concrete structure, the same below) is a new subject currently facing us. For more than 30 years since the founding of the People’s Republic of China, due to the shortage of steel, the height of urban construction has been limited by economic conditions. Therefore, before 1984, there was no new high-rise steel structure in China. With the implementation of the policy of opening up and invigorating the country, joint ventures with foreign countries are increasing, and due to the large population of the city
