| 摘 要： | 针对不同偏心率圆钢管混凝土短柱试件进行了试验,介绍了试验参数,试验装置和方法,得到荷载与应变、荷载与挠度曲线,分析了偏心率对该类构件力学性能的影响规律,并应用相关规程进行了极限承载力的验算。结果表明:随着偏心率的增大,钢管对核心混凝土的约束作用不断减弱,极限承载力也明显下降,而其横向变形能力逐渐减弱,在延性方面则影响不大。试件达到极限承载力时,其对应受压区的纵环向应变也比较大。

| Abstract: | Experiments were carried out on the short CFST columns subjected to different eccentricity.The test parameters,setups and methods are introduced.The Load and stain,load and deflection curves were obtained.The influence of the load eccentricity ratio on the behavior of eccentrically-loaded CFST columns was analyzed.The ultimate bearing capacity was checked by related statutes.The available suggestion about the application of the structure was obtained.The results indicate that with the increase of load eccen... |
