Chapter: to further accelerate the research on the technical system of steel structure construction

　　According to the arrangement and requirements of the ministry of housing and urban-rural development, in order to accelerate the process of combing and researching the technical system of steel structure construction, the China building metal structure association held the "expert seminar on combing the technical system of steel structure construction of the ministry of housing and urban-rural development" in xiaoshan, hangzhou on October 30, 2018.Meeting invited domestic famous experts and scholars engaged in research on steel structure housing, the leadership of the design institute, research institutes and experts, research and development of steel structure housing application results of corporate chief engineer, together constitute the system of steel structure building technology team, the domestic steel structure residence system, form a complete set of existing mature part and retaining system combing with the discussion.

　　As one of the main structural systems of prefabricated buildings, steel structure has the advantages of high degree of industrial production, good seismic performance of the structure, mature and reliable node connection technology, etc., and has become the preferred structural form in the popularization and application of prefabricated buildings.In order to further promote the development of steel structure building, touch clear true state and the application status quo of domestic steel structure housing, in view of the current economic situation changes and new characteristics of infrastructure investment, "according to the special sea sand management continuously deepen situation", through the promotion of steel structure building and application of new wall materials, promote the development of the modern construction industry, deepen the reform of the housing market supply side structural to actively explore.

　　Meeting after expert discussion and brainstorming, the technology of steel structure building system combing focus on steel structure residence house system and form a complete set of product research and summarize, mainly around the steel structure building technology and application research report draft content of the framework are detailed discussed and put forward Suggestions, in order to ensure the smooth completion of the study, also has carried on the section of the division of labor and schedule at the meeting, by combing can be summarized the present situation of the application of existing steel structure residential housing system and the existing problems, clarify some fuzzy understanding of steel structure residential society,The technology and application level of steel structure building especially steel structure residence under the new situation will be improved continuously.The convening of this seminar is of great significance to accelerate the popularization and application of advanced mainstream technology system and product system of steel structure building.

　　During the meeting, the participants visited the assembly construction production base of hangxiao steel structure co., ltd. and the wanjun green building product experience center to enhance the intuitive feeling of the technical system of steel structure residential buildings and the application of enclosure plate engineering.
