摘　　要：作者设计了一种新型实腹式钢骨混凝土异形柱,为进一步研究这种新型构件的受力性能,进行了3根十字形钢骨混凝土异形柱和1根钢筋混凝土异形柱的轴心受压下的静力试验,对不同含钢骨率及无钢骨构件的力学性能进行了对比分析。发现钢骨混凝土异形柱与普通钢筋混凝土异形柱相比具有更高的承载力和更好的延性。这种新型实腹式钢骨混凝土异形柱可以在工程中推广使用。A new type of solid - web special - shaped steel reinforced concrete column was designed. In order to study its mechanical property, a static force test was conducted on three steel reinforced concrete special - shaped columns and one reinforced concrete special -shaped column under axial compression. Comparative analysis about components with different steel ratios was made. The results show that both the bearing capacity and ductility of special - shaped steel reinforced concrete column are better than those of common reinforced concrete special- shaped column. The new type solid -web special -shaped steel reinforced concrete column can be widely used in constructions.
