［摘要］對型鋼部分包裹再生混凝土短柱進行了軸壓試驗，考慮再生粗骨料取代率、混凝土強度、長細比等為變化參數(shù)，對其進行靜力試驗。結(jié)果表明：型鋼與再生混凝土具有良好的協(xié)同工作能力；該組合柱在軸壓下的受力過程可分為彈性階段、彈塑性工作階段和破壞階段；以型鋼翼緣屈曲、再生混凝土壓碎為破壞形式。
［關鍵詞］型鋼部分包裹再生混凝土短柱； 軸壓試驗； 混凝土取代率； 長細比

Abstract:Axial compression experiments were carried out on section steel partially encased recycled aggregate concrete short column. Static tests were carried out considering recycled coarse aggregate replacement rate, concrete strength and slenderness ratio. The results show that the section steel and recycled concrete have good cooperative working ability; the mechanical process of the composite column under axial compression can be divided into elastic stage, elastic-plastic stage and failure stage; the failure mode is the buckling of the steel flange and the crushing of recycled concrete.
Keywords:section steel partially encased recycled aggregate concrete short column; axial compression experiment; concrete replacement rate; slenderness ratio
