［摘要］針對工字型鋼-混凝土組合梁的受彎性能，建立了三維有限元數(shù)值分析模型，對試驗(yàn)全過程進(jìn)行了非線性數(shù)值模擬，計(jì)算結(jié)果與試驗(yàn)數(shù)據(jù)吻合較好。利用該模型，分析了工字型鋼混凝土組合梁的受力變形機(jī)理，探討了鋼梁強(qiáng)度等級(jí)、混凝土強(qiáng)度等級(jí)、鋼梁腹板厚度、混凝土板厚度及縱橫向配筋率等對組合梁受彎性能的影響，為工程設(shè)計(jì)提供參考依據(jù)。

Abstract:Threedimensional model of Ishaped steelconcrete composite beams was established in order to research the flexural behavior of composite beams. The whole experiment process was simulated nonlinearly. Comparisons between the experiment analysis and calculated results showed good correlation. The force mechanism of Ishaped steelconcrete beams was analyzed. The effects of the main parameters, such as steel strength grade, concrete strength grade, steel webs thickness, concrete plate thickness and reinforcement ratio, on flexural behavior were analyzed by using the presented model. The results derived from analysis provide some useful references for engineering design.

Keywords:composite beam; flexural behavior; interface slip; finite element analysis
