Abstract: In order to analyze the research hotspot and development trend of the BIM technology in the field of steel structure, this paper studies the research literature of CNKI database from 2014 to 2018, and analyzes the research hotspot and the development of BIM in the field of steel structure from the perspective of literature measurement by applying the method of social network analysis and multi-dimensional scale analysis with the aid of knowledge mapping tools. The results show that the key words in the research literature constitute the knowledge map network centered on "BIM" and "Steel Structure", and that the key word density reflects that the "Detailed Design" and "Construction" are two hot spots in the research with other related research hotspots including "High-Rise and Super-High-Rise Buildings", "Green Construction" and "Green Buildings". The multidimensional scale analysis concludes that the research topics are "Detailed Design" and "Construction". At last, the time map of CiteSpace shows that the research trend is in progress towards the prefabricated buildings and virtual construction.
