寿县合兴浅谈中国钢结构建筑比例有很大提升空间

发布时间:2016-3-25 10:31:01 浏览次数:575

在钢结构工业发展成熟的国家,钢结构在建筑结构中的占比普遍超过40%,美国钢结构建筑占比在大多数年份都在40%以上,1999年达到56%;日本20世纪90年代钢结构建筑占比达到39%。英国新增建筑90%以上是钢结构。根据中国钢结构协会的数据,2012年中国使用钢结构的建筑占比仅6%。


In the steel structure industry development mature countries, steel structure in building structure accounted for the ratio of more than 40% in general, steel structure building in the United States accounted for than in most years are in more than 40%, 1999 reached 56%; Japan's in the 1990s construction steel structure accounted for 39%. The new building is more than 90% of steel structure. According to the China Steel Association data, 2012 China use steel structure building accounted for only 6%.


钢结构工业的高速发展期一般为20-25年,随后进入成熟稳定期,此时钢结构产量占钢铁产量的比重约为20%-30%。美国钢结构的高速发展期为1953-1975年,日本为1955-1975年,大概持续20-25年。进入成熟期以后,美国钢结构产量的峰值为5000万吨,对应的钢产量约1.1亿吨,占比达到45%,之后该比例有所降低,维持在20-30%左右;日本钢结构产量稳定在年均2500万吨的水平,钢产量稳定在1亿吨左右,占比约25%。


The high speed development period of the steel structure industry is generally 20-25 years, and then enter the mature and stable period. At this time, the proportion of the steel structure production accounts for the steel output is about 20%-30%. The rapid development of the U.S. steel structure for 1953-1975 years, the Japanese for 1955-1975 years, about 20-25 years. After entering the mature stage, the peak value of the output of steel structure for 50 million tons, corresponding to the steel output of about 1.1 million tons, accounted for to reach more than 45%, the proportion decreased, maintained at 20-30%; Japan steel structure production stable at an annual average of 2500 million tons of levels, steel output stable at around 1 billion tons, accounting for approximately 25%.


2001年起,我国钢铁行业正式步入快速发展时期,年均增速超过20%,2008年受金融危机影响增速有所放缓,之后维持10%左右的水平,但钢结构行业仍处于逐步发展阶段,目前钢结构产量占粗钢的比重仅为5.6%。


In 2001, China's iron and steel industry formally entered the period of rapid development, with an average annual growth rate of over 20%, 2008 by the impact of the financial crisis has slowed down, after maintaining the level of about 10%, but the steel structure industry is still in the progressive stages of development, the current steel structure production accounted for crude steel than the weight of only 5.6%.
