摘　　要：目的设计一种新型十字形截面钢骨混凝土异型柱,研究其受力性能及破坏机理.方法对3根含钢率不同的十字形截面钢骨混凝土异形短柱和1根无钢骨的十字形截面普通混凝土异形柱进行单向偏压试验.结果十字形截面钢骨混凝土异型柱的承载力要比无钢骨的普通钢筋混凝土异形柱的承载力平均高出54%,随着含钢率的增大,构件的承载力及延性相应增加.结论十字形截面钢骨混凝土异形柱中的钢骨与混凝土能够较好的共同工作直至破坏,这种新型十字形截面钢骨混凝土异型柱为组合结构的发展提供了一种新的结构形式.The purpose of this paper is to give a new concept to the steel reinforced concrete special- shaped columns designing and to find its stressed performance, the mechanism of its destruction and the method of its computation. In order to do these, we made three cruciform steel reinforced concrete special - shaped short columns and one ordinary reinforced concrete short column, and subjected them to eccentric load. Thus, we researched the characteristics of the destruction of the columns and the influence of the proportion of steel on the ductility and the supporting capacity. The result shows that the steel and the concrete can work well together. The supporting capacity is much higher than that of the ordinary reinforced concrete Column and the experiment provides a new form for the innovation of the structure.
