我国执行开放政策以来,美、日、德等国来华投资日益增多。在这些建筑技术先进的国家内,都以钢结构建筑为主,故对中国很少采用钢结构深为不解。目前我国钢产量逐年增多,计划经济逐步向市场经济转轨,工程建设开始注重投资效益。由于自然科学有它自身发展的规律,因此不少建筑界人士认为我国建筑钢结构在它适用的范围内今后必然会有较大的发展。正如网架钢结构,在五、六十年代开始发展,虽在七十年代一度困难重重,但目前却已在国内全面开花。这也说明科学发展有其目身的规律。目前,民用高层钢结构是国内钢结构领域中唯一 Since the implementation of the open policy in China, investment from the United States, Japan and Germany to China has increased. In these countries with advanced construction technologies, steel construction is the mainstay, so it is difficult to understand the seldom use of steel structures in China. At present, China’s steel production has increased year by year, the planned economy has gradually shifted to a market economy, and engineering construction has begun to focus on investment returns. Since the natural sciences have their own laws of development, many people in the construction industry believe that China’s construction steel structure will inevitably have greater development in the future. Just as the steel structure of the grid began to develop in the 1950s and 1960s, although it was once difficult in the 1970s, it has now fully emerged in China. This also shows that scientific development has its own laws. At present, civil high-rise steel structures are the only ones in the field of domestic steel structures.
