轴心受压下L形型钢混凝土异形柱延性的研究

Ductility performance of L-shaped steel reinforced concrete columns under axial compression

为进一步研究型钢混凝土异形柱构件的受力性能,文章设计了一种新型实腹式型钢混凝土异形柱,进行了3根L字形型钢混凝土异形柱和1根钢筋混凝土异形柱的轴心受压下的静力试验,并对不同含型钢率及无型钢构件的力学性能进行了对比分析。试验结果表明型钢混凝土异形柱比普通钢筋混凝土异形柱具有更好的延性。

To study the mechanical property of the specially-shaped column of steel reinforced concrete,a new typical solid-web steel reinforced concrete specially-shaped column was designed.Static tests were conducted on 3 steel reinforced concrete special-shaped columns and 1 reinforced concrete special-shaped column under axial pressure.The mechanical property of the components with various shaped steel content and those without steel were compared.The results show that the ductility of specially-shaped column is better than that of normal reinforced concrete special-shaped column of steel reinforced concrete.
