摘　　要：针对宝钢三期1580热轧、1420/1550冷轧及二炼钢连铸等工程中改进的钢管混凝土双肢柱单腹板肩梁,进行了4个轴压比为0.1,缩尺比为1∶3的单腹板肩梁模型试件的水平单调加载试验研究.对单腹板肩梁的试验现象进行了描述,分析了肩梁腹板的主应变分布规律,得到了肩梁试件的承载力和破坏模式,并将试验结果与现行的肩梁设计方法进行了比较,以期对这种肩梁形式的受力性能和设计方法有进一步的认识.Monotonic tests were carried out on improved single-web shoulder-beam specimens with double concrete-filled steel tube column used in the project of the third period of BaoSteel 1580 hot rolling mill,1420/1550 cold rolling mill,and second steel making mill to study their behaviors,which consist of four 1：3 scaled models under increased horizontal load with constant axial ratio of 0.1. Test phenomenon was described,and stress distribution in the web of the shoulder-beam analyzed. Based on the test results,the bearing capacity and failure mode were obtained and compared with the current design method of shoulder-beam,which may lead to further understanding about the characteristic of this kind of shoulder-beam.
