[摘要]钢结构具有轻质、高强、易于工业化和可持续发展等优点，伴随着我国经济的发展而迅速发展，在目前我国大力提倡工业化生产这一时期显得更具发展前景，但与发达国家相比，我国钢结构的应用范围和发展方式还存在一定的差距。美国作为钢结构历史悠久、发展成熟的发达国家，有很多值得我们学习的地方。通过探究美国钢结构的发展历史、应用范围及应用特点等，对国内钢结构的发展和设计提供一些参考和借鉴。

Abstract: Steel structure which has the advantages of light weight, high strength, easy to industrialization and sustainable development is developing rapidly with the development of our country′s economy. In the current our country vigorously promote industrialization production, the steel structure is more development prospects, but compared with developed countries, there are still some gaps in the application and development of steel structure in China. As a developed country with a long history and mature development, the United States has a lot to learn, through studying the development history, application range and characteristics of the steel structure of the United States to provide some reference for the development and design of the domestic steel structure.

Keywords: steel structure of the United States； application history； application range； characteristic
