中文摘要：

采用纤维截面法编制了再生混凝土L形柱N-M曲线和Mx-My曲线的计算程序,研究了再生混凝土强度等级、再生粗骨料取代率、轴压比和荷载角对再生混凝土L形柱正截面承载力的影响规律。结果表明：随着再生混凝土强度等级的提高,L形柱正截面承载力显著增加;随着取代率的增加,L形柱正截面承载力减小;当轴压比增加时,L形柱正截面承载力先增大后减小;当荷载角增加时,L形柱正截面承载力先减小后增加。

英文摘要：

In this paper, the fiber method was used to calculate the N - M interaction curves and Mx - Myinteraetion curves of recycled concrete L - shaped column sections. The influence of the strength grade of recycled concrete, recycled coarse aggregate replacement percentage, the axial compression ratio and the loading angle on the normal section bearing capacity of recycled concrete L - shaped column were analyzed. The results showed that as the strength grade of recycled concrete increases, the normal section bearing capacity augments remarkably. The normal section bearing capacity got smaller as the increase of the replacement percentage. With the rise of the axial compression ratio, the normal section bearing capacity increased initially and then decreased. With the rise of the loading angle, the normal section bearing capacity decreased firstly and then increased.
