摘要
对6根焊接普通H型钢部分包裹混凝土组合短柱进行了偏心受压试验的研究,主要考虑含钢率、翼缘宽厚比等因素.试验结果表明,钢与混凝土能够很好地协同工作,达到最大荷载前,翼缘没有发生局部屈曲.这种组合结构柱最终的破坏模式为混凝土压碎,横向系杆间翼缘发生局部屈曲.
The results were described about the six short column tests of the partially encased concrete（PEC） composite columns made with welded H-section steel under eccentric load.The main factors influencing the ultimate load capacity of the PEC column were steel ratio and width-to-thickness ratio of the flange.The test results indicated that steel and concrete could work together and the flange buckling did not occur before the peak load between the links.Failure of all columns was due to local buckling of the flanges along with the concrete crushing.
