(河北理工大學(xué)建筑工程學(xué)院，唐山063000)[摘要] 針對索-混凝土組合梁這一新型結(jié)構(gòu)，利用有限元分析軟件ANSYS進(jìn)行自振特性分析，求出結(jié)構(gòu)的自振頻率及相應(yīng)的振型。隨后分析了索-混凝土組合梁結(jié)構(gòu)各項參數(shù)對自振特性的影響。這些參數(shù)包括索截面面積、索初始應(yīng)變、梁跨度、剛性桿高度。

Then it researched the affection of every parameter to the free vibration of structure. The parameter contains cable areas, cable initial strains, beam lengths and rigid link heights.
Keywords: cable-concrete combined beam; free vibration characteristics analysis
