摘要: 为了研究这种新型组合柱的受力性能,对9个焊接普通H型钢部分包裹混凝土组合短柱进行了轴压试验,试验主要考虑含钢率、翼缘宽厚比、横向系杆间距等对柱子的极限承载力的影响。通过分析得出,在不同含钢率下,影响PEC短柱承载力的因素。同时含钢率大小直接影响柱极限承载能力。

Abstract: In order to study force performance of a new column,it is described the test results of nine stub-columns with partially encased welded H-section steel.The test studies the effects of steel ratio,width-thickness ratio of flange and space of horizontal bar on ultimate strength of short column.It has been found out by analysis that on condition of different steel ratios,the ultimate bearing capacity of a column is affected directly by the bearing capacity of PEC short column under axial load and its influencing factors,as well as steel ratio.
