积极稳健推动高层建筑钢结构的发展

To promote development of steel structure for highrise building positively and steady

我国高层建筑长期以来都是以钢筋混凝土结构为主.近十几年来,通过大量实践,我国高层建筑结构技术已发展到一个较高水平,科研生产、设计制造等已逐步形成完整体系,高层建筑用H型钢的生产正在发展,钢管混凝土使用增多,尤其是符合我国国情的钢—混结构体系,在我国已获得越来越广泛的采用.进一步发展我国高层建筑钢结构,需要从结构钢的材质抓起,研制和生产各种适用和专用的钢型材、配套材料以及高强混凝土,充实相关的设计规范规程,加强对重大技术课题的科研实验,开展国内外信息交流,制定相应的技术政策等.此外,文中对国内外高层结构建筑,为抵抗风力引起的振动影响而采用的结构控制方法,作了较细的介绍.

For a long time past, main structure of highrise building in China is of reinforced concrete, In recent about twenty years, the technique of steel structure for highrise buildings at home has reached to a higher level after a great deal of practice. An integrated system of research, design, manufacture, construction and education for steel structure of highrise building has been formed progressively, production of H steel profile for highrise building is developing, application of steel pipe reinforced with concrete is increasing, especially steel - concrete structure system, conformed with the national conditions, have been adopted wider and wider.In order to make further development of steel structure for highrise building in China, the measures should be takan: at first pay attention to material quality of structural steel, research and fabrication of various suitable and special - use steel profile, matching materials and high strength concrete, supplement with related standards and regulations for design, increasement to research and test of major technigue problems, development of information exchange between home and abroad, drawing up appropriate technical policy, etc. In addition, the author introduces in detail several structural control methods to prevent vibration effect acted on highrise steel structure building caused by wind force.
