(1 清華大學土木工程系，北京100084； 2 浙江大學建筑工程學院，杭州310058)［摘要］采用有限元分析方法，通過改變構(gòu)件的跨度、腹板高度、翼緣寬度和厚度等幾何參數(shù)，系統(tǒng)研究了波形腹板H型鋼梁的抗剪性能，得到了不同的屈曲模態(tài)，并且通過與具有相同幾何尺寸和荷載邊界條件的普通H型鋼梁的比較，得到了結(jié)構(gòu)抗剪承載力受初始缺陷影響較小的結(jié)論。通過理論分析，得到了一個可以用來指導(dǎo)設(shè)計的抗剪承載力計算公式，具有較大的推廣價值。［關(guān)鍵詞］波形腹板；抗剪承載力；有限元分析中圖分類號：TU391.2文獻標識碼：A文章編號：1002-848X(2011)02-0049-03Finite element analysis on shear capacity of the corrugated web H-shaped steel beamPang Bo1,2, Nie Jianguo1, Dong Shilin2(1 Department of Civil Engineering, Tsinghua University, Beijing 100084, China;2 College of Civil Engineering & Architecture, Zhejiang University, Hangzhou 310058, China)Abstract:By changing the geometric parameters such as span, web height, flange width and thickness, the finite element analysis method was mainly used to systematically study the shearing behavior, and different buckling modes were got. By comparing with the common H-shaped steel beam with the same geometry and loading boundary conditions, the result that the corrugated web H-shaped steel beam has a better shearing strength was got.Through theoretical analysis, a shearing capacity formula was advised to guide the design, which has a great promotional value.Keywords:corrugated web; shear capacity; finite element analysis作者簡介：龐礴，碩士，Email：longb03@gmail.com。參考文獻［1］劉磊, 錢冬生. 波形鋼腹板的受力行為［J］. 鐵道學報, 2002, 22(S1): 53-56.［2］SAYED-AHMED E Y.
