［摘要］通過6個型鋼再生混凝土組合柱的靜載試驗，對型鋼再生混凝土組合柱軸壓承載力進行了研究。試驗主要考慮再生粗骨料取代率和長細比兩個參數(shù)對構件承載力的影響。由試驗得出組合柱在軸心荷載下的荷載位移曲線，分析型鋼再生混凝土組合柱的破壞機理及再生粗骨料取代率、長細比對其軸壓承載力的影響，提出型鋼再生混凝土組合柱軸壓承載力計算公式。

［關鍵詞］型鋼再生混凝土； 取代率； 長細比； 承載力

 Abstract:According to static experiment of six steel reinforced recycled aggregate concrete composite columns，the axial compression loadbearing capacity was studied. Two factors, which were the recycled coarse aggregate replacement rate and slenderness ratio, were taken into consideration. Loaddisplacement curves of composite columns under axial loads were obtained. The fracture of composite columns and the influence of recycled coarse aggregate replacement rate and slenderness ratio on axial compression loadbearing capacity were analyzed. The formula for axial compression load of steel recycled concrete composite column was also presented.

Keywords:steel reinforced recycled aggregate concrete; replacement rate; slenderness ratio; loadbearing capacity
