(清華大學土木工程系,北京 100084)[摘要]波浪腹板工形截面構件由翼緣與波浪腹板組成,與平腹板工形截面構件相比具有較高的承載效率。由波浪腹板工形截面構件所組成的門式剛架,在國外工業(yè)建筑輕型房屋鋼結(jié)構工程中有較廣泛的應用,其經(jīng)濟效益也明顯優(yōu)于傳統(tǒng)的門式剛架結(jié)構。總結(jié)了筆者對波浪腹板工形截面構件在軸力、彎矩以及壓彎組合作用下的受力性能與設計方法的研究成果,并與同類型平腹板的工形截面構件的性能與設計方法進行了比較。介紹了波浪腹板門式剛架的節(jié)點構造,并給出了波浪腹板工形構件的制作等方面的要求。比較了波浪腹板構件與平腹板構件的承載效率,并結(jié)合一個典型的門式剛架工業(yè)廠房,比較了波浪腹板門式剛架體系與平腹板門式剛架體系在經(jīng)濟性等方面的差異。[關鍵詞]波浪腹板;門式剛架;力學性能;設計;制作中圖分類號:TU392.5文獻標識碼:A文章編號:1002-848X(2011)04-0011-09Design theory and application of steel structures of light-weight buildings with sinusoidal web gabled framesGuo Yanlin, Wang Xiao′an, Zhang Qinglin, Jiang Ziqin(Department of Civil Engineering, Tsinghua University, Beijing 100084, China)Abstract:Sinusoidal web H-shaped members are composed of flanges and sinusoidal webs, and are widely used in steel structures of light-weight industrial buildings overseas, which possess higher load-carrying efficiency and better economic benefit compared to traditional flat web members. Mechanical behaviors of sinusoidal web H-shaped members under various load cases including axial force, pure bending, and combined compression and bending were introduced, and design methods were proposed. Both joint details and fabrication requirements of the sinusoidal web gabled frames were presented. Carrying efficiencies of sinusoidal web members and flat web members were compared. Based on a typical industrial building, economic performances of buildings with sinusoidal web gabled frames and with traditional flat web gabled frames were compared.Keywords:sinusoidal web; gabled frame; mechanical behavior; design; fabrication作者簡介:郭彥林,教授,博士生導師,Email:gyl@tsinghua.edu.cn。參考文獻[1]張慶林. 波浪腹板工形構件穩(wěn)定承載力設計方法研究[D]. 北京:清華大學, 2008.[2]郭彥林,張慶林.波折腹板工形構件截面承載力設計方法[J]. 建筑科學與工程學報,2006, 23(4): 58-63.[3]郭彥林,張慶林,王小安.波浪腹板工形構件抗剪承載力設計理論及試驗研究[J]. 土木工程學報,2010, 43(10): 45-52.[4]郭彥林,張慶林,王小安. 波浪腹板梁平面外穩(wěn)定承載力設計理論與試驗研究[J]. 土木工程學報,2010, 43(11):17-26.[5]郭彥林,王小安,張慶林. 波浪腹板變截面壓彎構件穩(wěn)定承載力設計方法和試驗研究[J]. 工程力學,2010, 27(9): 139-146.[6]張慶林,郭彥林. 波浪腹板工形構件設計理論及其在門式剛架結(jié)構中的應用[C]//2007年全國輕型鋼結(jié)構技術研討會. 上海: 2007.[7]郭彥林,張慶林. 波折腹板工形構件翼緣穩(wěn)定性能研究[J]. 建筑科學與工程學報,2007, 24(4): 64-69.[8]EASLEY J T, MCFARLAND D E.
